Procedure

To a 0° C. solution of (2S,5R)-6-(benzyloxy)-7-oxo-1,6-diaza-bicyclo[3.2.1]octane-2-carboxylic acid (12.0 g, 43.5 mmol) and tert-butyl 4-hydrazinyl-4-oxobutylcarbamate (10.5 g, 47.8 mmol) in CH2Cl2 (360 mL) was added HATU (19.6 g, 52.2 mmol) and DIPEA (16.6 g, 130.5 mmol). The mixture was allowed to warm to rt, was stirred at rt for 12 hrs then diluted with CH2Cl2 (300 mL), washed with water (2×) and saturated sodium chloride (2×), dried over Na2SO4, and concentrated. The residue was purified by silica gel column chromatography (gradient elution 50˜80% EtOAc/petroleum ether) to afford tert-butyl 4-(2-((2S,5R)-6-(benzyloxy)-7-oxo-1,6-diaza-bicyclo[3.2.1]octane-2-carbonyl)hydrazinyl)-4-oxobutylcarbamate (19.3 g, 93%) as a white solid. ESI-MS (EI+, m/z): 476 [M+H]+.
