Procedure

Amino-acetic acid methyl ester (5 g, 40 mmol) was suspended in DMF and treated with triethylamine (13.9 mL, 100 mmol) and 2-chloro-benzoyl chloride (5 mL, 40 mmol). The reaction mixture was stirred at room temperature overnight. Water was added to the reaction, and the mixture was extracted with ethyl acetate three times. The organic layers were combined and dried over sodium sulfate, filtered and concentrated. The residue was purified by flash chromatography using ethyl acetate/hexane to yield (2-chloro-benzoylamino)-acetic acid methyl ester as a light yellow solid. LCMS calcd for C10H10ClNO3 (m/e) 227, obsd 228 (M+H).
