Procedure

20% palladium hydroxide on carbon (270 mg) was suspended in a MeOH (81 ml) solution of tert-butyl 4-[(benzyloxy)methyl]-4-methoxypiperidine-1-carboxylate (2.7 g), and stirred under a flow of hydrogen gas at room temperature for 4 hours. After filtering using Celite, the filtrate was concentrated, and the residue was purified by silica gel column chromatography (EtOAc) to obtain tert-butyl 4-(hydroxymethyl)-4-methoxypiperidine-1-carboxylate (1.55 g).
