tert-Butyl (3S,5R)-3-{[(benzyloxy)carbonyl]amino}-5-(morpholin-4-ylcarbonyl)piperidine-1-carboxylate (39 g) and palladium(II) hydroxide-carbon (4 g) were suspended in methanol (500 ml) and the mixture was stirred under a hydrogen atmosphere (1 atom) at room temperature for 15 hr. The palladium catalyst was filtered off, and the filtrate was concentrated under reduced pressure to give tert-butyl (3S,5R)-3-amino-5-(morpholin-4-ylcarbonyl)piperidine-1-carboxylate (28 g).
