Trifluoroacetic acid (0.5 mL, 6 mmol) was added to (S)-methyl 2-(tert-butoxycarbonylamino)-3-(4-(isopropylcarbamoyloxy)phenyl)propanoate in methylene chloride (2 mL). The reaction was stirred for 1 h, and was concentrated under reduced pressure to give crude product, methyl (2S)-2-amino-3-(4-{[(isopropylamino)carbonyl]oxy}phenyl)propanoate (50 mg, 100%). Analytical LCMS (M+H)+: m/z=281.0.
