Reaction Steps

Acetyl chloride (0.627 ml, 8.81 mmol) was added dropwise to a suspension of commercially available Z-Dap-OH ((S)-3-amino-2-(((benzyloxy)carbonyl)amino)propanoic acid) (1 g, 4.20 mmol) in methanol (20 ml) at 0° C. The mixture was stirred at 0° C. for 4 hours and at room temperature for 16 hours. The solvent was evaporated under vacuum to afford the title compound.
