Procedure

To a solution of 4-(4-chlorophenyl)-1-[3-(2-cyano-6,11-dihydrodibenz[b,e]oxepin-11-ylidene)propyl]piperidin-4-ol (380 mg) in EtOH (20 ml) were added Raney nickel (50% slurry in water, 60 mg), and the mixture was hydrogenated at 15 psi for 2 hours. The mixture was filtered through the celite and distilled off under reduced pressure. The residue was purified by silica gel chromatography eluting with dichloromethane-methanol-aqueous ammonium (95:5:1) to give the titled compound (130 mg).
