실험 절차

To a mixture of (2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxylic acid 1 (0.250 g, 0.905 mmol) in DCM (15.0 mL) were added 2-methoxyacetohydrazide 218 (0.141 g, 1.358 mmol), 1-hydroxybenzotriazole (0.186 g, 1.358 mmol) and 1-ethyl-(3-dimethylamino propyl) carbodiimide hydrochloride (0.260 g, 1.358 mmol) sequentially at room temperature. The mixture was stirred at room temperature overnight, diluted with DCM and concentrated to provide a residue, which was subjected to chromatography to give 219 (0.27 g, 82%) as a white foam.
