Procedure

A mixture of 6.5 parts of 5-(3-fluorophenyl)-1,2,3,6-tetrahydro-1-(phenylmethyl)pyridine hydrochloride and 120 parts of methanol was hydrogenated at normal pressure and at 50° C. with 1 part of palladium-on-charcoal catalyst 10%. After the calculated amount of hydrogen was taken up, the catalyst was filtered off and the filtrate was evaporated, yielding 4.5 parts (100%) of 3-(3-fluorophenyl)piperidine hydrochloride as a residue (intermediate 93).
