Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to certain cycloalkanones, cycloalkanols and unsaturated analogs thereof having from 5 to 8 carbon atoms in the cycloalkyl ring and at the 3-position a 2-hydroxy-4-(Z-W-substituted)phenyl group wherein Z is alkylene having from one to thirteen carbon atoms or (alk.sub.1).sub.m -O-(alk.sub.2).sub.n -wherein each of m and n is 0 or 1 and each of (alk.sub.1) and (alk.sub.2) is alkylene having from one to thirteen carbon atoms with the proviso that summation of carbon atoms in (alk.sub.1) plus (alk.sub.2) is not greater than thirteen; and W is hydrogen, phenyl, chlorophenyl, fluorophenyl or pyridyl; derivatives thereof, intermediates therefor and processes for their preparation. The products are useful as CNS agents, especially an analgesics, tranquilizers, sedatives and antianxiety agents in mammals, including man, and/or as anticonvulsants, diuretics and antidiarrheal agents in mammals, including man.

2. Description of the Prior Art

Despite the current availability of a number of analgesic agents, the search for new and improved agents continues, thus pointing to the lack of an agent useful for the control of broad levels of pain and accompanied by a minimum of side-effects. The most commonly used agent, aspirin, is of no practical value for the control of severe pain and is known to exhibit various undesirable side-effects. Other analgesic agents such as d-propoxyphene, codeine, and morphine, possess addictive liability. The need for improved and potent analgesic agents is, therefore, evident.

U.S. Pat. No. 3,576,887, issued Apr. 27, 1971, describes a series of 1-(1'-hydroxy)alkyl-2-o-hydroxyphenylcyclohexane or -ene compounds which serve as intermediates for production of 6,6-dialkyltetrahydro- and hexahydro- dibenzo[b,d]pyrans of use as central nervous system depressants.

U.S. Pat. No. 3,974,157 describes 2-phenylcyclohexanones as intermediates for preparation of 1-(aminoalkyl)-2-phenylcyclohexanols useful as analgesics, local anesthetics and antiarrhythmics. The 2-phenylcyclohexanones can be substituted in the phenyl ring with up to two alkyl, hydroxy or alkoxy group.

Chemical Abstracts 85, 176952f (1976) discloses a number of 3-phenyl- and 3-phenylalkylcyclohexanones as intermediates for 2-aminomethyl-3-phenyl (or phenalkyl)cyclohexanones which exhibit analgesic, sedative, antidepressant and anticonvulsant activities.

SUMMARY OF THE INVENTION

It has now been found that certain cycloalkanones, cycloalkanols, and unsaturated analogs thereof having at the 3-position a 2-hydroxy-4-(substituted)phenyl group (formula I below) are effective as CNS agents, especially as analgesics, tranquilizers, sedatives and antianxiety agents in mammals, including humans, and/or as anticonvulsants, diuretics and antidiarrheal agents in mammals, including man. Also included in this invention are various derivatives of said compounds which are useful as dosage forms of the compounds, intermediates for compounds having formula I, and methods for their preparation. The compounds have the formula: ##STR1## wherein R is selected from the group consisting of saturated and unsaturated cycloalkyl moieties selected from the group consisting of ##STR2## wherein

Z is selected from the group consisting of (a) alkylene having from one to thirteen carbon atoms; (b) --(alk.sub.1).sub.m --O--(alk.sub.2).sub.n --wherein each of (alk.sub.1) and (alk.sub.2) is alkylene having from one to thirteen carbon atoms, with the proviso that the summation of carbon atoms in (alk.sub.1) plus (alk.sub.2) is not greater than thirteen; each of m and n is 0 or 1; and

W is selected from the group consisting of hydrogen, pyridyl, ##STR3## wherein W.sub.1 is selected from the group consisting of hydrogen, fluoro and chloro.

The broken lines in formula I compounds, i.e. formulae IA-ID, represent the optional presence of a double bond at one of said locations.

Also included in this invention are the pharmaceutically acceptable acid addition salts of those compounds of formulae I which contain a basic group. Typical of such compounds are those wherein the W variable is pyridyl and/or OR.sub.1 represents a basic ester moiety.

Cis-relationship between the substituent at the 1- position of the cycloalkyl moiety and the phenolic, or substituted phenolic, moiety at the 3- position is favored, and trans-relationship between the 3- and 4-substituents and the 4- and 5-substituents on the cycloalkyl moiety are favored because of the greater (quantitatively) biological activity. For the same reason, the trans-3,4-relationship is also favored in compounds of formula IA-ID wherein A and B when taken together represent oxo.

For convenience, the above formulae depict the racemic compounds. However, the above formulae are considered to be generic to and embracive of the racemic modifications of the compounds of this invention, the diastereomeric mixtures, the pure enantiomers and diastereomers thereof. The utility of the racemic mixture, the diastereomeric mixture as well as of the pure enantiomers and diastereomers is determined by the biological evaluation procedures described below.

DETAILED DESCRIPTION OF THE INVENTION

The saturated cycloalkyl compounds of this invention having formula I wherein R.sub.3 is hydrogen are prepared from the appropriate 2-bromo-5-(Z-W substituted)phenol by a series of reactions which comprises as first step protection of the phenolic group. Suitable protecting groups are those which do not interfere with the subsequent reactions and which can be removed under conditions which do not cause undesired reactions at other sites of said compounds or of products produced therefrom. Representative of such protective groups are methyl, ethyl, benzyl or substituted benzyl wherein the substituent is, for example, alkyl having from one to four carbon atoms, halo (Cl, Br, F, I) and alkoxy having from one to four carbon atoms. The ether protecting, or blocking, groups can be removed throuth the use of hydrobromic acid in acetic acid or hydrobromic acid, 48% aqueous. The reaction is conducted at elevated temperatures and desirably at the reflux temperature. However, when Z is --(alk.sub.1).sub.m --O--(alk.sub.2).sub.n --, acids such as polyphosphoric acid or trifluoroacetic acid must be used to avoid cleavage of the ether linkage. Other reagents such as hydriodic acid, pyridine hydrochloride or hydrobromide can be used to remove protecting ether groups such as methyl or ethyl groups. When the protecting groups are benzyl or substituted benzyl groups, they can be removed by catalytic hydrogenolysis. Suitable catalysts are palladium or platinum, especially when supported on carbon. Alternatively they can be removed by solvolysis using trifluoroacetic acid. A further procedure comprises treatment with n-butyllithium in a reaction-inert solvent at room temperature.

The exact chemical structure of the protecting group is not critical to this invention since its importance resides in its ability to perform in the manner described above. The selection and identification of appropriate protecting groups can easily and readily be made by one skilled in the art. The suitability and effectiveness of a group as a hydroxy protecting group are determined by employing such a group in the herein-illustrated reaction sequences. It should, therefore, be a group which is easily removed to regenerate the hydroxy groups. Methyl and benzyl are favored protecting groups since they are readily removed.

The protected 2-bromo-5-(Z-W substituted)phenol is then reacted with magnesium in a reaction-inert solvent and generally in the presence of a promoter, e.g., cuprous salts such as the chloride, bromide and iodide (to promote 1,4-addition) with the appropriate 4-R.sub.2 -2-cycloalken-1-one (e.g., 4-R.sub.2 -2-cyclohexen-1-one). Suitable reaction-inert solvents are cyclic and acyclic ethers such as, for example, tetrahydrofuran, dioxane and dimethyl ether of ethylene glycol (diglyme). The Grignard reagent is formed in known manner, as, for example, by refluxing a mixture of one molar proportion of the bromo reactant and two molar proportions of magnesium in a reaction-inert solvent, e.g. tetrahydrofuran. The resulting mixture is then cooled to about 0.degree. C. to -20.degree. C., and cuprous iodide added followed by the appropriate 2-cycloalken-1-one at a temperature of from about 0.degree. C. to -20.degree. C. The amount of cuprous iodide used is not critical but can vary widely. Molar proportions ranging from about 0.2 to about 0.02 moles per mole of bromo reactant afford satisfactory yields of the cycloalkanone wherein the phenolic hydroxy group is protected (formulae IA-ID, R.sub.1 =a protecting group; R.sub.3 =H; A+B=oxo).

The protected cycloalkanone is then treated with an appropriate reagent to remove the protecting group. The benzyl group is conveniently removed by the method described above. If the protecting group is an alkyl group (methyl or ethyl) it is removed by the above-mentioned methods or by treatment with, for example, pyridine hydrochloride.

When R.sub.2 is an alkenyl group, the cycloalkenones thus produced serve as intermediates for preparation of the corresponding cycloalkenones (IA-ID) wherein R.sub.2 is alkyl.

The cycloalkanol compounds having formula I are prepared from the protected cycloalkanones by reduction. Sodium borohydride is favored as reducing agent in this step since it not only affords satisfactory yields of the desired product, but retains the protecting group on the phenolic hydroxy group, and reacts slowly enough with hydroxylic solvents (methanol, ethanol, water) to permit their use as solvents. Temperatures of from about -40.degree. C. to about 30.degree. C. are generally used. Lower temperatures, even down to about -70.degree. C., can be used to increase selectivity of the reduction. Higher temperatures cause reaction of the sodium borohydride with the hydroxylic solvent. If higher temperatures are desired, or required for a given reduction, isopropyl alcohol or the dimethyl ether of diethylene glycol are used as solvents. Sometimes favored as reducing agent is potassium tri-sec-butyl borohydride since it favors stereoselective formation of the trans-1,3-phenylcycloalkanol. The reduction is conducted in dry tetrahydrofuran at a temperature below about -50.degree. C. using equimolar quantities of the ketone compound and reducing agent.

Reducing agents such as lithium borohydride, diisobutylaluminum hydride or lithium aluminum hydride which can also be used require anhydrous conditions and non-hydroxylic solvents, such as 1,2-dimethoxyethane, tetrahydrofuran, diethyl ether, dimethyl ether of ethylene glycol.

The cycloalkanols of formula I wherein A is hydrogen and each of B and OR.sub.1 is hydroxy can, of course, be obtained directly by catalytic reduction of the protected cycloalkanone over palladium-on-carbon or by catalytic reduction or chemical reduction of the unprotected cycloalkanone (formula I, A+B=oxo, OR.sub.1 =OH) using the reducing agents described above.

In actual practice it is preferred to produce the unprotected cycloalkanols of formula I (A=H, B=OR.sub.1 =OH) via reduction of the benzyl protected cycloalkanones (formula I, A+B=oxo, OR.sub.1 =benzyloxy) as described above, since it permits stereochemical control of the reduction and formation of the cis-hydroxy epimer as the major product and thus facilitates separation and purification of the epimeric alcohols.

Compounds of formulae IA-ID wherein the double bond is at the 2,3-positions are prepared by Grignard reaction of the appropriate protected 2-bromo-5-(Z-W substituted)phenol with a 3-alkoxy-2-cycloalken-1-one (having from one to four carbon atoms in the alkoxy group) in a reaction-inert solvent at a temperature of from about -30.degree. C. to +10.degree. C. The protected cycloalkenone compound thus produced is then deprotected as described above and reduced to the corresponding cycloalkenol. Alternatively, the protected cycloalkenone is reduced chemically, e.g. using sodium borohydride, to the protected cycloalkenol which is then deprotected to regenerate the phenolic hydroxy group.

Compounds of formulae IA-ID wherein the double bond is at the 3,4-position are prepared from compounds of formulae IA-ID wherein A+B is oxo and the double bond is at the 2,3-position. The process comprises ketalization of the appropriate 2,3-unsaturated formulae IA-ID compounds with an alkylene glycol having from two to four carbon atoms in the presence of a dehydrating agent such as p-toluenesulfonic acid in a solvent such as benzene which permits azeotropic removal of by-product water. Isomerization of the double bond to the 3,4-unsaturated ketal derivative occurs. Deketalization by mild acid treatment affords the 3,4-unsaturated compounds of formulae IA-ID wherein A+B represent oxo. Reduction of the oxo group as described above affords the corresponding alcohol.

The protected cycloalk-2-enones (formulae IA-ID, A+B=oxo, R.sub.1 =protecting group) also serves as intermediates for formula I compounds wherein R.sub.3 is methyl. Introduction of the R.sub.3 substituent is achieved by conjugate addition of dimethylcopper lithium to the appropriate cycloalk-2-enone. The process comprises reacting the appropriate protected cycloalkenone with dimethylcopper lithium, in a reaction-inert solvent, such as cyclic and acyclic ethers and especially in tetrahydrofuran, at from about 0.degree. C. to -20.degree. C. The organometallic reagent effects 1,4-addition to the protected cycloalkenone with formation of a tertiary carbon. The R.sub.3 -substituted protected cycloalkanone is then deprotected and reduced, or reduced and then deprotected according to procedures described above. The 1,2-addition product is also formed.

Compounds of formula IB wherein the cycloalkyl moiety is saturated and wherein R.sub.4 is other than hydrogen are prepared by reacting the appropriate 2-bromo-5-(Z-W-substituted)phenol, in which the phenolic group is suitably protected as described above, with magnesium to form the Grignard reagent as previously described. The resulting Grignard reagent is then treated, without isolation, at a reduced temperature, e.g., about +10.degree. C. to about -20.degree. C. with N,N-dimethylformamide. The reaction mixture is then allowed to warm to room temperature and the product, a protected 2-hydroxy-4-(Z-W-substituted)benzaldehyde, recovered by known methods. The benzaldehyde derivative is then converted to an .omega.-(2-hydroxy-4-(Z-W-substituted)phenyl)-3-alken-one via the Wittig reaction with the appropriate 1-triphenylphosphoranylidene-2-alkanone in a reaction-inert solvent at a temperature of from about room temperature to the reflux temperature of the solvent. The 2-propanone derivative mentioned above permits formation of the cyclohexyl moiety. The aryl alken-one thus produced is then reacted with a dialkylmalonate, preferably one in which the alkyl groups have from 1-4 carbon atoms, to cyclize the alken-one. The reaction is conducted in a reaction-inert solvent, such as an alcohol having from 1-4 carbon atoms, at a temperature of from about 25.degree. C. to about the reflux temperature of the solvent.

The carbalkoxy substituted cycloalkanedione compound produced is then decarboxylated by treatment with aqueous sodium or potassium hydroxide at an elevated temperature; that is, from about 50.degree. C. to 100.degree. C., and the cycloalkanedione derivative isolated by standard, known methods. It is then ketalized by reaction with methanol, or other alcohol having up to 4 carbon atoms, or an alkylene glycol having from 2 to 4 carbon atoms, in the presence of a dehydrating acid such as p-toluenesulfonic acid.

In the case of the cyclohexyl derivative, the 3-methoxy-2-cyclohexene-1-one derivative is then reacted with lithium aluminum hydride in a reaction-inert solvent such as diethyl ether, dioxane, tetrahydrofuran or diglyme at a temperature of about -10.degree. C. to 10.degree. C. and worked up with dilute mineral acid. The resulting aryl substituted-2-cyclohexene-1-ones are then treated with the appropriate dialkylcopper lithium in a suitable reaction-inert solvent such as hexane, diethyl ether, or mixtures of these solvents or in cyclic ethers such as tetrahydrofuran at a temperature of from about 0.degree. C. to about -20.degree. C. The protected 3-[4-(Z-W)-substituted-2-hydroxyphenyl]-5-R.sub.4 cycloalkanone is then deprotected and reduced, or reduced and then deprotected, according to procedures previously described.

Alternatively, reaction of the 5-[2-benzyloxy-4-(Z-W)phenyl]-3-alkoxy-2-cyclohexen-1-ones with the appropriate Grignard reagent R.sub.4 MgBr followed by acid hydrolysis produces the corresponding 5-[2-benzyloxy-4-(Z-W)phenyl]-3-R.sub.4 -2-cyclohexen-1-ones which are then catalytically reduced to the corresponding cyclohexanones. Debenzylation, as described above, affords the 5-[2-hydroxy-4-(Z-W)-phenyl]-3-R.sub.4 -cyclohexanones which are then reduced as described above to the corresponding cyclohexanols.

Compounds of formula I-C wherein the cycloalkyl moiety is saturated and wherein R.sub.4 is other than hydrogen are prepared by ring expansion of the cyclohexyl derivative. Reaction of the appropriate 5-[2-benzyloxy-4-(Z-W)-phenyl]-3-R.sub.4 -cyclohexanone with lithium dibromomethane in a reaction-inert solvent such as diethyl ethers affords the 1-dibromomethyl-5-[2-benzyloxy-4-(Z-W)-phenyl]-3-R.sub.4 -cyclohexanol. Further reaction of the 1-dibromomethyl cyclohexanol in a reaction-inert solvent such as tetrahydrofuran with n-butyl lithium yields 3-[2-hydroxy-4-(Z-W)-phenyl]-5-R.sub.4 -cycloheptanones which are then deprotected and reduced, or reduced and deprotected, according to procedures previously described.

Compounds of formula I-D wherein the cycloalkyl moiety is saturated and wherein R.sub.4 is other than hydrogen are prepared by ring expansion of the cycloheptyl derivative, according to procedures previously described.

When R.sub.4 is hydrogen in structure IA-IC it is possible, according to procedures previously described, to cause ring expansion of these structures to the one methylene larger ring; i.e., to IB-ID, respectively.

The 2-bromo-5-(Z-W substituted)phenol reactants are prepared by bromination of the appropriate 3-(Z-W substituted)phenol according to standard procedures as, for example, by treatment with bromine in carbon tetrachloride at a temperature of from about 20.degree. C.-30.degree. C. The necessary 3-(Z-W substituted)phenols, if not known compounds, are prepared by procedures illustrated herein. A convenient method for preparing such reactants wherein the Z moiety is alkylene or (alk.sub.1).sub.m -O-(alk.sub.2).sub.n - comprises the Wittig reaction on an appropriate aldehyde such as 2-(3-hydroxyphenyl)-2-methyl propionaldehyde, the hydroxy group of which is protected by benzyl ether formation. The said aldehyde is then treated with the appropriate alkyltriphenylphosphonium bromide, the alkyl group of which extends the propionaldehyde group to the desired length. In a typical procedure, the aldehyde reactant is added to a slurry of sodium dimsyl and alkyl triphenylphosphonium bromide in dimethyl sulfoxide at a temperature below 30.degree. C., e.g. from about 10.degree. C. to 30.degree. C. When reaction is complete, the alkene substituted protected phenol is recovered by known methods. Hydrogenation of the alkene over palladium-on-carbon then affords the desired 3-(Z-W substituted)phenol benzyl ether. Judicious choice of the starting (3-hydroxyphenyl)substituted aldehyde and alkyl triphenylphosphonium bromide reactants affords the required 3-(Z-W substituted)phenol reactants.

Preparation of the appropriate 4-R.sub.2 -2-cycloalken-1-one allows synthesis of the structures of formulae IA-D wherein R.sub.4 is hydrogen, according to procedures previously described. Reaction of the appropriate 1,3-cycloalkan-dione with an alcohol of from one to four carbon atoms and an acid catalyst such as p-toluenesulfonic acid in a reaction-inert solvent such as benzene or toluene, and with an apparatus for water separation at temperatures where the reaction solvent will reflux affords 3-alkoxy-2-cycloalken-1-ones. Reacting the appropriate 3-alkoxy-2-cycloalken-1-one with lithiodiisopropylamide in a reaction-inert solvent such as tetrahydrofuran in the presence of hexamethylphosphoramide and the appropriate R.sub.2 X, where X is bromide or iodide or some other suitable leaving group, yields 4-R.sub.2 -3-alkoxy-2-cycloalken-1-ones. The 4-R.sub.2 -3-alkoxy-2-cycloalken-1-one is then reacted with lithium aluminum hydride in a reaction-inert solvent such as diethyl ether at temperatures of about -10.degree. C. to 10.degree. C. and worked up with dilute mineral acid. The resulting 4 -R.sub.2 -2-cycloalken-1-one is then transformed according to procedures already described.

Compounds of formula IB-ID wherein the cycloalkyl moiety is saturated and wherein each of R.sub.2 and R.sub.4 is other than hydrogen are prepared by reacting the appropriate 5-[2-benzyloxy-4-(Z-W)phenyl]-3-methoxy-2-cyclohexen-1-one with lithiodiisopropylamide in a reaction-inert solvent at a low temperature, e.g., -50.degree. C. to -78.degree. C. Hexamethylphosphoramide and the appropriate R.sub.2 iodide (wherein R.sub.2 is other than hydrogen) are then added to produce a 5-[2-benzyloxy-4-(Z-W)phenyl]-3-methoxy-6-R.sub.2 -2-cyclohexen-1-one. Further reaction of said compound with the appropriate Grignard reagent R.sub.4 'MgX (wherein R.sub.4 ' is alkyl) under usual Grignard reaction conditions affords a 3-[2-benzyloxy-4-(Z-W)phenyl]-4-R.sub.2 -5-R.sub.4 '-5-cyclohexen-1-one. Debenzylation and reduction of said compound according to procedures described above provides the desired 3-[2-hydroxy-4-(Z-W)-phenyl]-4-R.sub.2 -5-R.sub.4 '-cyclohexanol. Reduction of the double bond of the 3-[2-benzyloxy-4-(Z-W)phenyl]-4-R.sub.2 -5-R.sub.4 '-5-cyclohexen-1-one over Pd/C affords the corresponding saturated cyclohexanone derivative. These latter derivatives serve as intermediates for preparation of corresponding cycloheptanone and cyclooctanone derivatives by the ring expansion procedure described above.

A convenient procedure which permits selective alkylation of 3-(2,4-dihydroxyphenyl)cycloalkanones at the 4-hydroxy group comprises, as the first step, conversion of the 3-(2,4-dihydroxyphenyl)cycloalkanone to a ketal. The conversion is accomplished according to well-known procedures for ketalization, such as reaction of the 3-(2,4-dihydroxyphenyl)cycloalkanone with an alcohol, especially an alcohol having from one to four carbon atoms, in the presence of an acid, such as sulfuric acid, p-toluenesulfonic acid, hydrogen chloride, under conditions which remove the by-product water. A favored procedure comprises reaction of the 3-(2,4-dihydroxyphenyl)cycloalkanone with an orthoformic ester in solution in an alcohol corresponding to the alcohol moiety of the orthoformic ester. Trimethyl orthoformate and methanol are favored reactants along with concentrated sulfuric acid, anhydrous hydrogen chloride, or ammonium chloride as catalyst.

The ketal thus produced is then alkylated by reaction with an appropriate alkylating agent such as W-Z-X wherein W and Z are as defined above, and X is selected from the group consisting of chloro, bromo, mesyloxy (CH.sub.3 --SO.sub.2 --O) and tosyloxy (p--CH.sub.3 --C.sub.6 H.sub.4 --SO.sub.2 --O--) in the presence of an acid acceptor, e.g. sodium or potassium carbonate. The alkylated ketal is then deketalized according to known procedures by treatment with aqueous acid.

A further procedure for making 3-(Z-W substituted)phenols wherein Z is alkylene or (alk.sub.1)-O-(alk.sub.2).sub.n - comprises the Wittig reaction on an appropriate phenolic aldehyde or ketone, e.g., 3-hydroxybenzaldehyde or a 3-(hydroxyphenyl)alkyl ketone, in which the phenolic hydroxy group is protected as by conversion to the benzyl, methyl or ethyl ether. By choice of appropriate reactants, compounds having straight or branched alkylene groups (Z) can be produced. When a ketone, e.g. 3-hydroxyacetophenone, is used as reactant, compounds wherein Z has a methyl group on the carbon atom adjacent to the phenyl group are obtained.

Substitution of a methyl or ethyl group at other sites, e.g., the beta-carbon atom of the alkylene group, is achieved by choice of the appropriate carboalkoxy alkylidene triphenylphosphorane, e.g., (C.sub.6 H.sub.5).sub.3 P.dbd.C(R')-COOC.sub.2 H.sub.5. The unsaturated ester thus produced is reduced to the corresponding alcohol by reaction with lithium aluminum hydride. Alternatively, when the phenolic protecting group is other than benzyl (e.g. methyl), the alcohol is produced by catalytic reduction of the unsaturated ester using palladium-carbon, followed by treatment of the saturated ester thus produced with lithium aluminum hydride. Conversion of the alcohol thus produced to the corresponding tosylate or mesylate followed by alkylation of the tosylate or mesylate with an alkali metal salt of the appropriate HO-(alk.sub.2)-W reactant, and finally removal of the protecting group affords the desired 3-(Z-W substituted)phenol.

A variation of the above sequence comprises bromination of the alcohol rather than converting it to a tosylate or mesylate. Phosphorous tribromide is a convenient brominating agent. The bromo derivative is then reacted with the appropriate HO-(alk.sub.2)-W in the presence of a suitable base (Williamson ether synthesis).

The bromo compounds also serve as valuable intermediates for increasing the chain length of the alkylene moiety in the above sequence to give compounds wherein Z is -alkylene-W. The process comprises treating the bromo derivative with triphenylphosphine to produce the corresponding triphenylphosphonium bromide. Reaction of the triphenylphosphonium bromide with the appropriate aldehyde or ketone in the presence of a base such as sodium hydride or n-butyl lithium affords an unsaturated derivative which is then catalytically hydrogenated to the corresponding saturated compound.

An alternative method for introducing an alkyl or aralkyl group into the aromatic nucleus, and specifically such a group wherein the carbon atom adjacent the aromatic nucleus is a tertiary carbon atom, comprises acid catalyzed electrophilic aromatic substitution of guaiacol with a tertiary alcohol in the presence of an acid, e.g. methane sulfonic acid. The general procedure consists of reacting a mixture of methane sulfonic acid and equimolar amounts of guaiacol and tertiary alcohol at temperatures of from about 30.degree. C. to about 80.degree. C. until reaction is substantially complete. The product is isolated by pouring the reaction mixture onto ice followed by extraction with a suitable solvent such as methylene chloride. The 2-methoxy-4-alkyl phenol is then converted to the desired 3-alkyl phenol by removal of the phenolic hydroxy group. The process comprises converting the hydroxy group to a dialkyl phosphate group by reaction with a dialkyl chlorophosphonate, e.g. diethyl chlorophosphonate, or with diethyl phosphonate and triethylamine. Treatment of the dialkyl phosphate with lithium/ammonia followed by demethylation of the resulting alkylated methyl ether with boron tribromide or pyridine hydrochloride or other known demethylating agents affords the desired 3-alkylphenol.

A convenient method for preparing compounds of this invention wherein -Z-W is -O-(alk.sub.2).sub.n -W comprises the use of 4-bromo resorcinol as starting material. The process comprises protecting the two hydroxy groups of the resorcinol by benzylation according to standard procedures. The benzyl group is favored as protecting group in this method since it can easily be removed by catalytic hydrogenation without cleaving the ether group -O-(alk.sub.2).sub.n -W. Other protecting groups such as alkyl (e.g., methyl or ethyl) can, of course, also be used. However, the benzyl protecting group is favored since it gives rise to fewer side reactions. The protected 4-bromo resorcinol is then subjected to the Grignard reaction and reacted with the appropriate cycloalkenone in a reaction-inert solvent in the manner described above. The 3-(2,4-dibenzyloxyphenyl)cycloalkanone thus produced is then subjected to catalytic hydrogenation over palladium-on-carbon to produce the corresponding 3-(2,4-dihydroxyphenyl)cycloalkanone which exists in equilibrium with its hemiketal. The hemiketal is then converted to the corresponding C.sub.1-4 alkyl, e.g., methyl, ketal by reaction with, for example, a trialkyl orthoformate, such as trimethylorthoformate in a suitable solvent such as a C.sub.1-4 alcohol, e.g. methanol, in the presence of concentrated sulfuric acid. The thus-produced alkyl ketal is then alkylated with the appropriate alkyl or aralkyl methane sulfonate or tosylate in the presence of anhydrous sodium or potassium carbonate in a suitable reaction-inert solvent such as N,N-dimethylformamide at a temperature of from about 75.degree.-100.degree. C. This method has the advantage of permitting the use of simpler compounds throughout the entire sequence of reactions. The O-alkylated or aralkylated ketal is then deketalized by reaction with, for example, hydrochloric acid, to produce the corresponding 3-(2-hydroxy-4-[O-(alk.sub.2).sub.n ]phenyl)cycloalkanone which exists in equilibrium with its hemiketal.

Since compounds having formulae IA-ID in which A and B taken together are oxo and R.sub.1 is hydrogen exist in solution in equilibrium with the hemiketal form and some, in the crystalline state, exist substantially completely in the hemiketal form, compounds of formulae IA-ID wherein A and B taken together are oxo and R.sub.1 is hydrogen are intended to embrace the hemiketal as well as the keto form.

Compounds of this invention wherein A and B taken together are methylene are readily prepared from the corresponding oxo compounds via the Wittig reaction with methylene triphenylphosphorane or other appropriate methylide. The usual procedure comprises generating the Wittig reagent; that is, the methylide, in situ and, immediately following generation of the methylide, reacting it with the appropriate oxo compound. A convenient procedure for generating the methylide comprises reacting sodium hydride with dimethyl sulfoxide (sodium dimsyl) at a temperature of from about 50.degree.-80.degree. C., usually until evolution of hydrogen ceases, followed by reacting the resulting solution of methyl sulfinyl carbanion (dimsyl) with, for example, methyl triphenyl phosphonium bromide at a temperature of from about 10.degree. C. to about 80.degree. C. To the thus-produced solution of the ylide is then added the appropriate oxo compound and the mixture stirred at temperatures ranging from about room temperature to 80.degree. C. The methylene compound thus produced is isolated by known procedures. Hydroboration-oxidation of the methylene compound then affords the hydroxymethyl derivative as is exemplified herein. Borane in tetrahydrofuran is favored for the hydroboration step since it is commercially available and gives satisfactory yields of the desired hydroxymethyl compound. The reaction is generally conducted in tetrahydrofuran or diethylene glycol dimethyl ether (diglyme). The borane product is not isolated but is directly oxidized with alkaline hydrogen peroxide to the hydroxymethyl compound.

Other methods of generating the methylide are, of course, known and can be used in lieu of the above-described procedure. Typical procedures are described by Maercker, Organic Reactions, 14, 270 (1965). In the oxo compounds having formulae IA-ID, the phenolic hydroxy group can be protected if desired as, for example, by conversion to an alkanoyloxy derivative. Other protecting groups can, of course, be used. The hydroxyl group can be converted to ethers such as, for example, tetrahydropyranyl ethers. However, protection of the phenolic hydroxy group is not absolutely necessary if sufficient base is present to convert the phenolic hydroxy group to an alkoxide.

Esters of compounds of formulae IA-ID wherein R.sub.1 is alkanoyl or --CO--(CH.sub.2).sub.p NR.sub.5 R.sub.6 are readily prepared by reacting formulae IA-ID compounds wherein R.sub.1 is hydrogen with the appropriate alkanoic acid or acid of formula HOOC--(CH.sub.2).sub.p NR.sub.5 R.sub.6 in the presence of a condensing agent such as dicyclohexylcarbodiimide. Alternatively, they are prepared by reaction of a formulae IA-ID compound with the appropriate alkanoic acid chloride or anhydride, e.g., acetyl chloride or acetic anhydride, in the presence of a base such as pyridine.

Esters of compounds of formulae IA-ID wherein A is hydrogen and B is hydroxy or hydroxymethyl and OR.sub.1 is hydroxy are prepared by acylation according to the above-described procedures. Compounds in which only the R group (R.dbd.OH, CH.sub.2 OH) is acylated are obtained by mild hydrolysis of the corresponding diacyl derivative, advantage being taken of the greater ease of hydrolysis of the phenolic acyl group. The thus-produced compounds can then be acylated further with a different acylating agent to produce a diesterified compound having different ester groups.

The analgesic properties of the compounds of this invention are determined by tests using nociceptive stimuli.

TESTS USING THERMAL NOCICEPTIVE STIMULI

(a) Mouse Hot Plate Analgesic Testing

The method used is modified after Woolfe and MacDonald, J. Pharmacol. Exp. Ther., 80, 300-307 (1944). A controlled heat stimulus is applied to the feet of mice on a 1/8-inch thick aluminum plate. A 250 watt reflector infrared heat lamp is placed under the bottom of the aluminum plate. A thermal regulator, connected to thermistors on the plate surface, programs the heat lamp to maintain a constant temperature of 57.degree. C. Each mouse is dropped into a glass cylinder (61/2-inch diameter) resting on the hot plate, and timing is begun when the animal's feet touch the plate. The mouse is observed at 0.5 and 2 hours after treatment with the test compound for the first "flicking" movements of one or both hind feet, or until 10 seconds elapse without such movements. Morphine has an MPE.sub.50 =4-5.6 mg./kg. (s.c.).

(b) Mouse Tail Flick Analgesic Testing

Tail flick testing in mice is modified after D'Amour and Smith, J. Pharmacol. Exp. Ther., 72, 74-79 (1941) using controlled high intensity heat applied to the tail. Each mouse is placed in a snug-fitting metal cylinder, with the tail protruding through one end. This cylinder is arranged so that the tail lies flat over a concealed heat lamp. At the onset of testing an aluminum flag over the lamp is drawn back, allowing the light beam to pass through the slit and focus onto the end of the tail. A timer is simultaneously activated. The latency of a sudden flick of the tail is ascertained. Untreated mice usually react within 3-4 seconds after exposure to the lamp. The end point for protection is 10 seconds. Each mouse is tested at 0.5 and 2 hours after treatment with morphine and the test compound. Morphine has an MPE.sub.50 of 3.2-5.6 mg./kg. (s.c.).

(c) Tail Immersion Procedure

The method is a modification of the receptacle procedure developed by Benbasset, et al., Arch. int. Pharmacodyn., 122, 434 (1959). Male albino mice (19-21 g.) of the Charles River CD-1 strain are weighed and marked for identification. Five animals are normally used in each drug treatment group with each animal serving as its own control. For general screening purposes, new test agents are first administered at a dose of 56 mg./kg. intraperitoneally or subcutaneously, delivered in a volume of 10 ml./kg. Preceding drug treatment and at 0.5 and 2 hours post drug, each animal is placed in the cylinder. Each cylinder is provided with holes to allow for adequate ventilation and is closed by a round nylon plug through which the animal's tail protrudes. The cylinder is held in an upright position and the tail is completely immersed in the constant temperature waterbath (56.degree. C.). The endpoint for each trial is an energetic jerk or twitch of the tail coupled with a motor response. In some cases, the endpoint may be less vigorous post drug. To prevent undue tissue damage, the trial is terminated and the tail removed from the waterbath within 10 seconds. The response latency is recorded in seconds to the nearest 0.5 second. A vehicle control and a standard of known potency are tested concurrently with screening candidates. If the activity of a test agent has not returned to baseline values at the 2-hour testing point, response latencies are determined at 4 and 6 hours. A final measurement is made at 24 hours if activity is still observed at the end of the test day.

TEST USING CHEMICAL NOCICEPTIVE STIMULI

Suppression of Phenylbenzoquinone Irritant-Induced Writhing

Groups of 5 Carworth Farms CF-1 mice are pretreated subcutaneously or orally with saline, morphine, codeine or the test compound. Twenty minutes (if treated subcutaneously) or fifty minutes (if treated orally) later, each group is treated with intraperitoneal injection of phenylbenzoquinone, an irritant known to produce abdominal contractions. The mice are observed for 5 minutes for the presence or absence of writhing starting 5 minutes after the injection of the irritant. MPE.sub.50 's of the drug pretreatments in blocking writhing are ascertained.

TESTS USING PRESSURE NOCICEPTIVE STIMULI

Effect on the Haffner Tail Pinch Procedure

A modification of the procedure of Haffner, Experimentelle Prufung Schmerzstillender. Deutch Med. Wschr., 55, 731-732 (1929) is used to ascertain the effects of the test compound on aggressive attacking responses elicited by a stimulus pinching the tail. Male albino rats (50-60 g.) of the Charles River (Sprague-Dawley) CD strain are used. Prior to drug treatment, and again at 0.5, 1, 2 and 3 hours after treatment, a Johns Hopkins 2.5-inch "bulldog" clamp is clamped onto the root of the rat's tail. The endpoint at each trial is clear attacking and biting behavior directed toward the offending stimulus, with the latency for attack recorded in seconds. The clamp is removed in 30 seconds if attacking has not yet occurred, and the latency of response is recorded as 30 seconds. Morphine is active at 17.8 mg./kg. (i.p.).

TESTS USING ELECTRICAL NOCICEPTIVE STIMULI

The "Flinch-Jump" Test

A modification of the flinch-jump procedure of Tenen, Psychopharmacologia, 12, 278-285 (1968) is used for determining pain thresholds. Male albino rats (175-200 g.) of the Charles River (Sprague-Dawley) CD strain are used. Prior to receiving the drug, the feet of each rat are dipped into a 20% glycerol/saline solution. The animals are then placed in a chamber and presented with a series of 1-second shocks to the feet which are delivered in increasing intensity at 30-second intervals. These intensities are 0.26, 0.39, 0.52, 0.78, 1.05, 1.31, 1.58, 1.86, 2.13, 2.42, 2.72 and 3.04 mA. Each animal's behavior is rated for the presence of (a) flinch, (b) squeak and (c) jump or rapid forward movement at shock onset. Single upward series of shock intensities are presented to each rat just prior to, and at 0.5, 2, 4 and 24 hours subsequent to drug treatment.

Results of the above tests are recorded as percent maximum possible effect (%MPE). The %MPE of each group is statistically compared to the %MPE of the standard and the predrug control values. The %MPE is calculated as follows: ##EQU1##

The compounds of this invention, when used as analgesics via oral or parenteral administration, are conveniently administered in composition form. Such compositions include a pharmaceutical carrier selected on the basis of the chosen route of administration and standard pharmaceutical practics. For example, they can be administered in the form of tablets, pills, powders or granules containing such excipients as starch, milk sugar, certain types of clay, etc. They can be administered in capsules, in admixtures with the same or equivalent excipients. They can also be administered in the form of oral suspensions, solutions, emulsions, syrups and elixirs which may contain flavoring and coloring agents. For oral administration of the therapeutic agents of this invention, tablets or capsules containing from about 0.01 to about 100 mg. are suitable for most applications.

The physician will determine the dosage which will be most suitable for an individual patient and it will vary with the age, weight and response of the particular patient and the route of administration. Generally, however, the initial analgesic dosage in adults may range from about 0.1 to about 750 mg. per day in single or divided doses. In many instances, it is not necessary to exceed 100 mg. daily. The favored oral dosage range is from about 1.0 to about 300 mg./day; the preferred dose is from about 1.0 to about 50 mg./day. The favored parenteral dose is from about 0.1 to about 100 mg./day; the preferred range from about 0.1 to about 20 mg./day.

This invention also provides pharmaceutical compositions, including unit dosage forms, valuable for the use of the herein described compounds as analgesics and other utilities disclosed herein. The dosage form can be given in single or multiple doses, as previously noted, to achieve the daily dosage effective for a particular utility.

The compounds (drugs) described herein can be formulated for administration in solid or liquid form for oral or parenteral administration. Capsules containing drugs of this invention are prepared by mixing one part by weight of drug with nine parts of excipient such as starch or milk sugar and then loading the mixture into telescoping gelatin capsules such that each capsule contains 100 parts of the mixture. Tablets containing said compounds are prepared by compounding suitable mixtures of drug and standard ingredients used in preparing tablets, such as starch, binders and lubricants, such that each tablet contains from 0.10 to 100 mg. of drug per tablet.

Suspensions and solutions of these drugs, particularly those wherein R.sub.1 (formulae I and II) is hydroxy, are often prepared just prior to use in order to avoid problems of stability of the suspensions or solution (e.g. precipitation) of the drug upon storage. Compositions suitable for such are generally dry solid compositions which are reconstituted for injectable administration.

By means of the above procedures, the analgesic activity of several compounds of this invention is determined. The compounds have the formula shown below: ##STR7##

The following abbreviations are used in the Tables: PBQ=phenylbenzoquinone-induced writhing; TF=tail flick; HP=hot plate; RTC=rat tail clamp; and FJ=flinch jump.

Single values in the tables are ED.sub.50 's. A number followed by a second number in parentheses reports the % protection observed at a given dose. Thus, 31(56) indicates 31% protection at a dose of 56 mg./kg. of body weight.

Their activity as diuretic agents is determined by the procedure of Lipschitz et al., J. Pharmacol., 197, 97 (1943) which utilizes rats as the test animals. The dosage range for this use is the same as that noted above with respect to the use of the herein described compounds as analgesic agents.

Antidiarrheal utility is determined by a modification of the procedure of Neimegeers et al., Modern Pharmacology-Toxicology, Willem van Bever and Harbans Lal, Eds., 7, 68-73 (1976). Charles River CD-1 rats (170-200 gms.) are housed in group cages 18 hours before testing. The animals are fasted overnight with water available ad libitum prior to administration of castor oil. The test drug is administered subcutaneously or orally at a constant volume of 5 ml./kg. of body weight in a 5% ethanol, 5% Emulphor EL-620 (a polyoxyethylated vegetable oil emulsifying agent available from Antara Chemicals, New York, N.Y.), and 90% saline vehicle followed one hour later with a challenge of castor oil (one ml., orally). The animals are placed in small individual cages (20.5.times.16.times.21 cm.) having suspended wire floors. A disposable cardboard sheet is placed beheath the wire floors and examined one hour after castor oil challenge for the presence or absence of diarrhea. A vehicle/castor oil treatment group serves as control for each day's testing. Results are recorded as the number of animals protected at one hour post challenge. In general, the dosage levels for use of these compounds as antidiarrheal agents parallels those with respect to their use as analgesic agents.

The tranquilizer activity of the compounds of this invention is determined by orally administering them to rats at doses of from about 0.01 to about 50 mg./kg. of body weight and observing the subsequent decreases in spontaneous motor activity. The daily dosage range in mammals is from about 0.01 to about 100 mg.

Anticonvulsant activity is determined by subcutaneously administering the test compound to male Swiss mice (Charles River) weighing 14-23 g. in a vehicle of the type used for antidiarrheal utility. The mice are used in groups of five. The day before use, the mice are fasted overnight but watered ad lib. Treatments are given at volumes of 10 ml. per kg. via a 25 gauge hypodermic needle. Subjects are treated with the test compound and, one hour after challenge, electroconvulsive shock, 50 mA. at 60 Hz. administered transcorneally. Controls are simultaneously run in which the mice are given only the vehicle as control treatment. The electroconvulsive shock treatment produces tonic extensor convulsions in all control mice with a latency of 1.5-3 seconds. Protection is recorded when a mouse exhibits no tonic extensor convulsions for 10 seconds after administration of electroconvulsive shock.

Antianxiety activity is determined in a manner similar to that for evaluating anticonvulsant activity except that the challenge convulsant is pentylenetetrazole, 120 mg./kg. administered intraperitoneally. This treatment produces clonic convulsions in less than one minute in over 95% of control mice treated. Protection is recorded when the latency to convulse is delayed at least 2-fold by a drug pretreatment.

Sedative/depressant activity is determined by treating groups of six mice subcutaneously with various doses of test agents. At 30 and 60 minutes post treatment, the mice are placed on a rotorod for one minute and evaluated for their performance on the rotorod. Inability of the mice to ride the rotorod is taken as evidence of sedative/depressant activity.

EXAMPLE 1

3-[2-Benzyloxy-4-(1,1-dimethylheptyl)phenyl]cyclohexanone

A solution of 75.0 g. (0.193 mol.) of 2-(3-benzyloxy-4-bromophenyl)-2-methyloctane in 200 ml. of tetrahydrofuran was slowly added to 9.25 g. (0.386 mol.) of 70-80 mesh magnesium metal. The resultant mixture was refluxed for 20 minutes and then cooled to -18.degree. C. Cuprous iodide (1.84 g., 9.7 mmoles) was added and stirring was continued for 10 minutes. To the resultant mixture was slowly added a solution of 18.5 g. (0.193 mol.) of 2-cyclohexen-1-one in 40 ml. of tetrahydrofuran at such a rate that the reaction temperature was maintained below -3.degree. C. with salt-ice cooling. The reaction mixture was stirred 30 minutes longer (t<0.degree. C.) and then added to 500 ml. of 2 N hydrochloric acid and 2 liters of ice water. The quenched reaction was extracted three times with 500 ml. portions of ether. The combined extract was washed twice with 100 ml. portions of water, twice with 100 ml. portions of saturated sodium chloride, dried over magnesium sulfate and evaporated to an oil. The oil was purified via column chromatography on 1.6 kg. of silica gel, eluted with 20% ether-cyclohexane to yield 62.5 g. (79.7%) of product as an oil.

To a -40.degree. C. solution of 43.0 g. (0.106 mol) of 3-[2-benzyloxy-4-(1,1-dimethylheptyl)phenyl]cyclohexanone in 500 ml. of methanol and 15 ml. of tetrahydrofuran was added, in three portions, 8.05 g. (0.212 mol.) of sodium borohydride. The reaction mixture was stirred for one hour at -40.degree. C., allowed to warm to -10.degree. C. and was then quenched by the addition of 100 ml. of saturated sodium chloride. The quenched reaction was added to 1500 ml. of water and extracted with three 450 ml. portions of ether. The combined ether extract was washed with three 100 ml. portions of water and two 200 ml. portions of saturated sodium chloride, dried over magnesium sulfate and evaporated to an oil. The oil was purified via column chromatography on 400 g. of silica gel eluted with 20% ether-cyclohexane to yield, in order of elution, 5.0 g. (12%) of trans-3-[2 -benzyloxy-4-(1,1-dimethylheptyl)-phenyl]cyclohexanol.

Ethyl 3-(3-Benzyloxyphenyl)crotonate (Wittig Reaction)

A mixture of 3-benzyloxyacetophenone (29.4 g., 0.13 mole) and carbethoxymethylenetriphenylphosphorane (90.5 g., 0.26 mole) is heated under a nitrogen atmosphere at 170.degree. C. for 4 hours. The clear melt is cooled to room temperature, triturated with ether and the precipitate of tripheynyl phosphine oxide removed by filtration. The filtrate is concentrated under vacuum to an oily residue which is chromatographed over silica gel (1500 g.) and eluted with benzene:hexane solutions of increasing benzene concentration beginning with 40:60 and ending with 100% benzene. Concentration of appropriate fractions gives the product as an oily residue.

PREPARATION M

3-(3-Benzyloxyphenyl)butyl Tosylate

A solution of ethyl 3-(3-Benzyloxyphenyl)crotonate (17.8 g., 60 mmole) in ether (250 ml.) is added to a mixture of lithium aluminum hydride (3.42 g., 90 mmole) and ether (250 ml.). Aluminum chloride (0.18 g., 1.35 mmole) is added and the mixture refluxed for 12 hours and then cooled. Water (3.4 ml.), sodium hydroxide (3.4 ml. of 6 N) and water (10 ml.) are then added successively to the reaction mixture. The inorganic salts which precipitate are filtered off and the filtrate is then concentrated in vacuo to give the 3-(3-benzyloxyphenyl)butanol as an oil.

Tosyl chloride (11.1 g., 58.1 mmole) is added to a solution of 3-(3-benzyloxyphenyl)-1-butanol (14.5 g., 57 mmole) in pyridine (90 ml.) at -45.degree. C. The reaction mixture is held at -35.degree. C. for 18 hours and is then diluted with cold 2 N hydrochloric acid (1500 ml.) and extracted with ether (5.times.200 ml.). The combined extracts are washed with saturated sodium chloride solution (4.times.250 ml.) and then dried (Na.sub.2 SO.sub.4). Concentration of the dried extract affords the product as an oil.

PREPARATION N

3-(3-Benxyloxyphenyl)-1-phenoxybutane

A solution of phenol (4.56 g., 48.6 mmole) in dimethylformamide (40 ml.) is added under a nitrogen atmosphere to a suspension of sodium hydride (2.32 g., 48.6 mmole) of 50% previously washed with pentane) in dimethylformamide (70 ml.) at 60.degree. C. The reaction mixture is stirred for one hour at 60.degree.-70.degree. C., after which a solution of 3-(3-benzyloxyphenyl)butyl tosylate (18.9 g., 46 mmole) in dimethylformamide (80 ml.) is added. The reaction mixture is stirred at 80.degree. C. for a half hour and is then cooled to room temperature, diluted with cold water (2500 ml.) and extracted with ether (4.times.400 ml.).

Debenzylation of the products according to the procedure of Preparation E affords the corresponding 2-bromo-5-[(alk.sub.1)-O-(alk.sub.2).sub.n -W]phenolbenzyl ethers which are brominated via the procedure of Preparation E. Benzylation of the thus produced bromophenols by the procedure of Example F affords the benzyl ether of the 2-bromo-5-[(alk.sub.1)-O-(alk.sub.2).sub.m -W]phenols.

PREPARATION O

4-(3-hydroxyphenyl)-1-(4-pyridyl)pentane

A mixture of 3-(3-methoxyphenyl)butyl triphenylphosphonium bromide (17.5 g., 35.4 mmoles) in dimethylsulfoxide (50 ml.) is added to 4-pyridinecarboxaldehyde (3.79 g., 35.4 mmoles) in tetrahydrofuran (40 ml.). The resulting mixture is then added dropwise to a slurry of 50% sodium hydride (1.87 g., 39 mmoles) in tetrahydrofuran (20 ml.) under a nitrogen atmosphere at 0.degree.-5.degree. C. and then concentrated under reduced pressure. The concentrate is diluted with water (200 ml.) and then acidified with 6 N HCl. The aqueous acid solution is extracted with benzene (4.times.50 ml.). It is then made basic and extracted with benzene (3.times.50 ml.). Evaporation of the combined extracts after drying (MgSO.sub.4) affords 4-(3-methoxyphenyl)-1-(4-pyridyl)-1-pentene as an oil.

Catalytic hydrogenation of the thus-produced pentene derivative in ethanol at 45 p.s.i. in the presence of Pd/C (1 g. of 10%) and concentrated HCl (1 ml.) affords the title product.

The pentane derivative thus obtained is dimethylated by heating a mixture of the compound (25 mmoles) and pyridine hydrochloride (35 g.) under a nitrogen atmosphere at 210.degree. C. for 8 hours. The hot mixture is poured into water (40 ml.) and the resulting solution made basic with 6 N sodium hydroxide. Water and pyridine are removed by distillation in vacuo. Ethanol (50 ml.) is added to the residue and the inorganic salts which precipitate are filtered off. The filtrate is concentrated in vacuo and the residue chromatographed on silica gel using as eluting agent 5% ethanol/benzene (4 liters), 10% ethanol/benzene (1 liter), 13% ethanol/benzene (1 liter) and 16% ethanol/benzene (5 liters).
