Trifluoroacetic acid (0.5 mL, 6 mmol) was added to the (S)-methyl 2-(tert-butoxycarbonylamino)-3-(4-isopropoxyphenyl)propanoate in methylene chloride (2 mL). The reaction was stirred for 1 h., and was concentrated under reduced pressure to give a crude product, methyl (2S)-2-amino-3-(4-isopropoxyphenyl)propanoate (40 mg, 100%) as colorless oil. Analytical LCMS (M+H)+: m/z=238.0.
