반응 단계
2-tert-Butoxycarbonylamino-butyric acid (500 mg, 2.46 mmol), HBTU (1.03 g, 2.71 mmol) and DIPEA (1.22 mL, 7.38 mmol) were dissolved in DMF (10 mL) and stirred for 30 min. N,O-dimethylhydroxylamine hydrochloride (360 mg, 3.69 mmol) was added and the reaction mixture was stirred for 1 h. The solvents were removed in vacuo and the residue was purified by column chromatography to give the title compound (380 mg, 63%) as a cream oil. LCMS (ES+): 269.2 [MNa]+.
