Reaction Steps
(S)-3-(4-nitro-phenylamino)-pyrrolidine-1-carboxylic acid tert-butyl ester was deprotected with trifluoroacetic acid according to known procedures. After concentration, the amine trifluoroacetate salt was treated with ethyl chloroformate (1 equiv.) and triethylamine (3 equiv.) in methylene chloride to afford (S)-3-(4-nitro-phenylamino)-pyrrolidine-1-carboxylic acid ethyl ester. LCMS calcd for C13H17N3O4 (m/e) 279.3, obsd 280.1 (M+H).
