実験手順
A solution of (2S,3S)-benzyl 3-azido-2-(tert-butoxycarbonylamino)butanoate (1.7 g, 5.08 mmol) and PdC (5%, wet) (340 mg, 319 μmol) in MeOH (16.4 g, 20.7 ml) was shaken under H2 (50 PSI) for 3.5 h, then filtered through a bed of celite and concentrated to give (2S,3S)-3-amino-2-(tert-butoxycarbonylamino)butanoic acid (1.15 g, quant.) as a white solid.
