Procedure

To a solution of compound (2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxylic acid 1 (0.193 g, 0.70 mmol) in dry DCM (20 mL) were added tert-butyl 3-(aminooxy)azetidine-1-carboxylate 36 (0.198 g, 1.05 mmol, J. Med. Chem. 2008, 51, 4601-4608), 1-hydroxybenzotriazole (0.142 g, 1.05 mmol) and 1-ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.201 g, 1.05 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 tert-butyl 3-[({[(2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]oct-2-yl]carbonyl}amino)oxy]azetidine-1-carboxylate 37 (0.15 g, 48%) as a clear thick oil.
