tert-Butyl (2S)-2-((3S)-3-{(2-amino-2-oxoethyl)[(6-chloro-2-naphthyl)sulfonyl]amino}-2-oxopyrrolidin-1-yl)propanoate (1.4 g) was dissolved in DCM (35 ml), and trifluoroacetic acid (35 ml) was added. The mixture was stirred at room temperature for 2 h and then evaporated under reduced pressure. The residue was azeotroped with anhydrous dichloromethane and then dried under high vacuum. The residual viscous oil was triturated with diethyl ether to give the title compound (1.23 g) as a white solid.
