Procedure

A mixture of 27.8 parts of 4-[bis(4-fluorophenyl)methylene]-1-(phenylmethyl)-3-piperidinol hydrochloride and 200 parts of methanol was hydrogenated at normal pressure and at room temperature with 3 parts 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. The residue was suspended in 80 parts of acetonitrile. The product was filtered off and dried, yielding 21.9 parts (100%) of 4-[bis(4-fluorophenyl)methylene]-3-piperidinol hydrochloride; mp.>260° C. (intermediate 24).
