Procedure
A solution of ethyl 2-[[2-[[(benzyloxy)carbonyl]amino]propyl](tert-butoxycarbonyl)amino]acetate (2.3 g) and 10% Pd/C (0.23 g) in methanol (46 ml) was stirred at room temperature for 1 hour under a hydrogen atmosphere. The catalyst was filtered off and the filtrate was stirred at 50° C. for 1 hour, concentrated under reduced pressure to obtain the title compound (1.1 g) as a colorless non-crystalline powder.
