실험 절차

(Benzyl-methyl-amino)-acetic acid hydrochloride salt (12 g, 56 mmol, 1.0 equiv) was mixed in DMF (200 mL) along with EDC (10.6 g, 56 mmol, 1.0 equiv) for 15 min. N,O-Dimethylhydroxylamine hydrochloride (6.52 g, 67 mmol, 1.2 equiv) was added to the reaction followed by N-methylmorpholine (34 mL, 334 mmol, 6.0 equiv). The reaction was stirred for 16 h. The DMF was removed in vacuo and the residue was redissolved in 200 mL of EtOAc. The solution was washed once with 200 mL brine. The organic layer was dried over Na2SO4, decanted and concentrated to yield the desired product as a free-flowing oil (12.6 g, 80%) that was used in the next step without further purification; MS, m/z 223=M+1.
