反应详情

A mixture of 1.5 gm (4.7 mMol) 1-benzyl-4-hydroxy-4-(naphth-1-yl)piperidine and 0.1 gm 5% palladium on carbon in 45 mL methanol was stirred under a hydrogen atmosphere for 2 days at room temperature. The reaction mixture was then filtered through a bed of celite and the filtrate concentrated under reduced pressure. The residue was subjected to flash silica gel chromatography, eluting with dichloromethane containing 17% methanol. Fractions containing product were combined and concentrated under reduced pressure to provide 0.526 gm (49%) of the title compound as a white solid.
