To a mixture of isatoic anhydride (250 mg, 1.53 mmol) and (S)-2-phenylglycine methyl ester hydrochloride (370 mg, 1.84 mmol) in DMF (5.0 mL) is added triethylamine (0.29 mL, 2.07 mmol). The mixture is stirred at room temperature for 16 hours. The reaction mixture is diluted with EtOAc (100 mL) and is washed with H2O (50 mL×3). The organic layer is dried over sodium sulfate and concentrated to afford (S)-(2-amino-benzoylamino)-phenyl-acetic acid methyl ester (330 mg, 76%).
