1-benzyl-4-[(1-cyclohexyl-3,4-dihydroisoquinolin-2(1H)-yl)carbonyl]piperidin-4-ol → 4-[(1-cyclohexyl-3,4-dihydroisoquinolin-2(1H)-yl)carbonyl]piperidin-4-ol

Reaction Steps

1-benzyl-4-[(1-cyclohexyl-3,4-dihydroisoquinolin-2(1H)-yl)carbonyl]piperidin-4-ol (220 mg) was dissolved in MeOH (12 mL), and 20% palladium hydroxide-supported activated carbon (360 mg) was added thereto, followed by stirring under a hydrogen atmosphere, at room temperature and normal pressure, for 15 hours. Thereafter, the catalyst was separated through celite. The solvent was evaporated to obtain 4-[(1-cyclohexyl-3,4-dihydroisoquinolin-2(1H)-yl)carbonyl]piperidin-4-ol (154 mg).
