Procedure

To a mixture of (2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxylic acid 1 (0.200 g, 0.723 mmol) in DCM (6.0 mL) was added tert-butyl {[2-(aminooxy)ethyl]sulfamoyl}carbamate 78 (0.276 g, 1.085 mmol), 1-hydroxybenzotriazole (0.147 g, 1.086 mmol) and 1-ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.208 g, 1.086 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 79 (0.35 g, 93%) as a white solid.
