Reaction Steps

A solution of 4-(3-benzyloxyphenyl)-1-(3,3-diphenyl-propyl)-4-fluoropiperidine hydrochloride (40 mg, 0.08 mmol) in methanol (5 mL) was treated with palladium on carbon (10 mg, 10% Pd, 50% H2O) and the mixture rapidly stirred under 1 atmosphere of hydrogen gas for 8 hours. After this time the hydrogen was replaced by nitrogen and the reaction mixture filtered through a celite pad. The pad was washed with additional methanol (10 mL) and the filtrate concentrated under reduced pressure. Trituration of the residue with a 1:1 mixture of 2-butanone/ethyl acetate (10 mL) and subsequent filtration and drying afforded a 64% yield of 1-(3,3-diphenylpropyl)-4-fluoro-4-(3-hydroxyphenyl)piperidine hydrochloride as an off-white solid.
