Procedure
To a mixture of (2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxylic acid 1 (0.210 g, 0.760 mmol, US 2005/20572 A1) in DCM (6.0 mL) were added tert-butyl {[2-(aminooxy)ethyl]carbamoyl}carbamate 84 (0.250 g, 1.140 mmol), 1-hydroxybenzotriazole (0.154 g, 1.140 mmol) and 1-ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.218 g, 1.140 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 85 (0.31 g, 85%) as a white solid.
