Procedure

To a mixture of (2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxylic acid 1 (0.200 g, 0.720 mmol, US2005/20572 A1) in DCM (6.0 mL) were added acetohydrazide 173 (0.090 g, 1.085 mmol), 1-hydroxybenzotriazole (0.147 g. 1.085 mmol). 1-ethyl-(3-dimethylamino propyl) carbodiimide hydrochloride (0.208 g, 1.085 mmol) and N,N-dimethylaminopyridine 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 174 (0.14 g, 60%) as a white foam.
