Procedure

Aqueous sodium hydroxide (1N; 3.81 mL, 3.81 mmol) was added to a solution of methyl N-[(benzyloxy)carbonyl]-O-{(1S)-2-[(tert-butoxycarbonyl)(cyclopropylmethyl)amino]1-phenylethyl}-D-serinate (1.30 g, 2.46 mmol) in tetrahydrofuran (20 mL). After 18 h, aqueous hydrochloric acid (1N; 3.81 mL, 3.81 mmol) was added. The mixture was extracted with dichloromethane (3×), and the combined organic extracts were dried over magnesium sulfate, filtered, and concentrated to give the title compound. (1.27 g) MS 535 (M+Na).
