Procedure

To a mixture of (2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxylic acid 1 (0.150 g, 0.543 mmol, US 2005/20572 A1) in DCM (10 mL) were added 4-(aminooxy)-1-methylpiperidine 50 (0.129 g, 0.99 mmol), 1-hydroxybenzotriazole (0.110 g, 0.814 mmol) and 1-ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.156 g, 0.814 mmol) sequentially at room temperature. The mixture was stirred at room temperature for 16 h, diluted with DCM, washed with water, brine, dried over sodium sulfate and concentrated to provide a residue which was subjected to chromatography to give 51 (0.065 g, 31%) as a yellow oil.
