Reaction Steps

A solution of 3-(2,2-diphenyl-1-ethenyl)-1-(3,4-methylenedioxyphenethyl)piperidine hydrochloride (135 mg) (Example 14) in EtOH (20 ml) was stirred at 40° C. under a hydrogen atmosphere of 45 psi in the presence of 10% palladium on charcoal. The mixture was filtered and the filtrate evaporated. The residue was partitioned between dichloromethane and 2M aqueous sodium hydroxide solution and the organic layer was dried over sodium sulphate and evaporated. The residue was purified by chromatography on silica using dichloromethane plus 2.5% methanol as eluant. Appropriate fractions were combined and evaporated to give the title compound as a colourless oil (60 mg, 50%) which was characterised as a hemihydrate.
