Reaction Conditions

Reaction Steps

Sodium ethylate prepared from sodium (0.23 g) and ethanol (10 ml) was added to ethyl 2-(3-mercaptophenyl)propionate (2.10 g) and the mixture was stirred for a while. Thereto was added trans-2-(chloromethyl)cyclohexanenitrile (1.58 g) and the resulting mixture was refluxed for 5 hours in an oil bath maintained at 100° C. The reaction mixture was evaporated to dryness under reduced pressure and to the residue was added toluene. After removal of the insoluble material by filtration, the solvent was distilled off under reduced pressure. The residue was chromatographed on silica gel, using chloroform as an eluent, to give ethyl 2-[3-(2-cyanocyclohexylmethylthio)phenyl]propionate (2.6 g) as an oil.
