Procedure

CF3COOH (5 mL) was slowly added at 0° C. to a solution of tert-butyl 4-(5-((2S,5R)-6-(benzyl-oxy)-7-oxo-1,6-diaza-bicyclo[3.2.1]octan-2-yl)-1,3,4-oxadiazol-2-yl)piperazine-1 carboxylate (723 mg, 1.5 mmol) in DCM (20 mL). The mixture was stirred at 0° C. for 3 hrs, then, the solvent was concentrated to afford (2S,5R)-6-(benzyloxy)-2-(5-(piperazin-1-yl)-1,3,4-oxadiazol-2-yl)-1,6-diaza-bicyclo[3.2.1]octan-7-one (997 mg) as a brown oil, which was used directly in the next step. ESI-MS (EI+, m/z): 385.1 [M+H]+.
