Reaction Steps
2-{[(tert-Butoxy)carbonyl]amino}acetic acid (5.00 g, 28.5 mmol) was dissolved in DCM (50 mL), CDI (5.09 g, 31.4 mmol) was added and the reaction mixture was stirred for 1 h. N,O-dimethylhydroxylamine hydrochloride (3.06 g, 31.4 mmol) was added and the reaction mixture was stirred for 16 h. EtOAc (150 mL) was added and the reaction mixture was washed with 1 M aq HCl (50 mL), sat aq NaHCO3 (2×50 mL), dried (Na2SO4) and concentrated in vacuo to give the crude title compound (5.13 g, 82%) as a white solid.
