Procedure

DIPEA (3.7 g, 10 mmol) was added to a 0° C. solution of (2S,5R)-6-(benzyloxy)-7-oxo-1,6-diaza-bicyclo[3.2.1]octane-2-carboxylic acid (1.45 g, 5.3 mmol, 0.8 eq.) and tert-butyl 4-(hydrazinecarbonyl)piperazine-1-carboxylate (1.6 g, 6.6 mmol) in dry DMF (50 mL), followed by the addition of HATU (1.45 g, 5.3 mmol). The reaction mixture was allowed to warm to rt then was stirred at rt overnight. The mixture was then diluted with water (200 mL) and the resulting precipitated material was collected by filtration, rinsed with water, and then recrystallized (3:1 petroleum ether/EtOAc) to afford tert-butyl 4-(2-((2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carbonyl)hydrazinecarbonyl)piperazine-1-carboxylate (1.4 g, 54%), ESI-MS (EI+, m/z): 503 [M+H]+.
