PROCEDURE

实验过程

(S)-tert-butyl 4-(4-((benzyloxycarbonyl)(methyl)amino)-5-(tert-butyldimethylsilyloxy)pentanoyl)piperazine-1-carboxylate (21.5 g) and 10% Pd/C (2.2 g) in ethanol (100 mL) was charged with H2 (50 psi). The resulting mixture was stirred at RT overnight and filtered. The filtrate was concentrated to give (S)-tert-butyl 4-(5-(tert-butyldimethylsilyloxy)-4-(methylamino)pentanoyl)piperazine-1-carboxylate (16 g, crude), which was sued without further purification. LRMS (M+H) m/z 430.3.
