Procedure

To a mixture of (2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxylic acid 1 (0.250 g, 0.905 mmol) in DCM (15.0 mL) were added tert-butyl 3-[(aminooxy)methyl]piperidine-1-carboxylate 152 (0.312 g, 1.358 mmol), 1-hydroxybenzotriazole (0.183 g, 1.358 mmol) and 1-ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.260 g, 1.358 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 153 (0.37 g, 84%) as a white foam.
