Procedure
A methanol (100 mL) solution of 4-[[(N-(benzyloxycarbonyl)glycyl)amino]methyl]-1-(tert-butoxycarbonyl)piperidine (6.26 g, 15.4 mmol) was hydrogenated in the presence of a 5% palladium carbon (620 mg) at room temperature for 7 hours. The catalyst was removed by filtration through Celite, and the filtrate was then concentrated to thereby afford 4-[(glycylamino)methyl]-1-(tert- butoxycarbonyl)piperidine as a solid (3.84 g, 92%).
