Procedure

To a solution of (R)-methyl 2-(benzyloxycarbonylamino)-3-(1-chloropropan-2-yloxy)propanoate (583 mg, 1.77 mmol) in THF—H2O (8 mL-4 mL) was added lithium hydroxide monohydrate (223 mg, 5.30 mmol). The mixture was stirred at room temperature for 25 minutes THF was removed in vacuo and the mixture extracted with EtOAc and dried over Na2SO4. Solvent was removed to give crude (R)-2-(benzyloxycarbonylamino)-3-(1-chloropropan-2-yloxy)propanoic acid as an oil. MS [M+H] found 316.2.
