The resulting mixture was transferred to an autoclave and charged with hydrogen (45 psi). The reaction mixture was stirred at RT for 1 h and filtered. The filtrate was concentrated to give (S)-tert-butyl 1-amino-3-(benzyloxy)propan-2-yl(methyl)carbamate, which was used without further purification. LRMS (M+Na+) m/z 317.2.
