실험 절차

To a solution of (2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxylic acid (0.25 g, 0.90 mmol) in dry dichloromethane (30 mL) were added 3,3-difluorocyclobutanecarbohydrazide 282 (0.20 g, 1.35 mmol), 1-hydroxybenzotriazole (0.19 g, 1.35 mmol), 1-ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.26 g, 1.35 mmol) and 4-(dimethylamino)pyridine (0.16 g, 1.35 mmol) at room temperature. The reaction mixture was stirred at room temperature overnight and concentrated under vacuum. The residue was purified by column chromatography to give 283 (0.32 g, 87%) as a white solid.
