Into a round-bottom flask was added methyl (2S)-2-[(benzyloxy)carbonyl]amino-3-[3-bromo-4-(1,1-dioxido-3-oxo-2-[2-(trimethylsilyl)ethoxy]methylisothiazolidin-5-yl)phenyl]-propanoate (165 mg, 0.252 mmol), dichloromethane (5 mL), and trifluoroacetic acid (2.5 mL). After stirring at room temperature for 30 minutes, the solvent was removed. The resulting residue was used in the next step without purification.
