実験手順

To a solution of (2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxylic acid 1 (0.25 g, 0.90 mmol) in dry DCM (40 mL) were added 3,3,3-trifluoropropanehydrazide 228 (0.19 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 (2R,5S)-6-(benzyloxy)-7-oxo-N′-(3,3,3-trifluoropropanoyl)-1,6-diazabicyclo[3.2.1]octane-2-carbohydrazide 229 (0.26 g, 72%) as a white solid.
