Procedure

To solution of (2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxylic acid 1 (0.20 g, 0.72 mmol) in dry DCM (25 mL) were added (4R)-4-(aminooxy)pyrrolidin-2-one 128 (0.12 g, 0.86 mmol, J. Med. Chem. 1997, 40(15), 2363-2373), 1-hydroxybenzotriazole (0.14 g, 1.10 mmol), 1-ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.20 g, 1.10 mmol) and 4-dimethylaminopyridine (0.13 g, 1.08 mmol) at room temperature. The reaction mixture was stirred at room temperature overnight, and then concentrated under vacuum. The residue was purified by column chromatography to give (2S,5R)-6-(benzyloxy)-7-oxo-N-{[(3R)-5-oxopyrrolidin-3-yl]oxy}-1,6-diazabicyclo[3.2.1]octane-2-carboxamide 129 (0.22 g, 82%) as a white solid.
