Procedure

To a solution of (2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxylic acid 1 (0.25 g, 0.90 mmol) in dry DCM (30 mL) were added tert-butyl (2S)-2-(hydrazinylcarbonyl)piperidine-1-carboxylate 270 (0.33 g, 1.35 mmol), 1-hydroxybenzotriazole (0.19 g, 1.35 mmol), 1-ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.26 g, 1.35 mmol) and 4-(dimethylamino)pyridine (0.16 g, 1.35 mmol) at room temperature. The reaction mixture was stirred at room temperature overnight and concentrated under vacuum. The residue was purified by column chromatography to give tert-butyl (2S)-2-[(2-{[(2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]oct-2-yl]carbonyl}hydrazinyl)carbonyl]piperidine-1-carboxylate 271 (0.37 g, 82%) as a white solid.
