Participants

Reaction Steps

A solution of 5.0 parts of 1,2-epoxy-3-(1-naphthoxy)-propane and 5.0 parts of 4-cyano-4-phenylpiperidine in 79 parts of ethanol is refluxed for 24 hours. Evaporation of the solvent from the reaction mixture under reduced pressure affords 3-(4-cyano-4-phenylpiperidino)-1-(1-naphthoxy)-2-propanol. The hydrochloride salt is then prepared by addition of a solution of hydrochloric acid in isopropanol to an isopropanol solution of the free amine. The resulting salt is separated by filtration and recrystallized from isopropanol to afford 3-(4-cyano-4-phenylpiperidino)-1-(1-naphthoxy)-2-propanol hydrochloride, melting at 213°-215° C. and represented by the following structural formula ##STR7##
