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 propanehydrazide 202 (0.120 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 203 (0.31 g, 99%) as a white foam.
