At room temperature, to a methanol solution (200 ml) of tert-butyl 4-{[(2R)-2-(benzyloxy)propanoyl]amino}piperidine-1-carboxylate (6.90 g) was added 10% palladium carbon (2.03 g), followed by stirring overnight under a hydrogen atmosphere. The reaction solution was filtered through Celite, and then concentrated under reduced pressure to afford tert-butyl 4-{[(2R)-2-hydroxypropanoyl]amino}piperidine-1-carboxylate (5.19 g).
