Procedure

A mixture of tert-butyl (2-(5-((2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]octan-2-yl)-1,3,4-oxadiazol-2-yl)ethyl)carbamate (400 mg, 0.90 mmol) and 10% Pd/C (50 mg) in THF (20 mL) was stirred under H2 atmosphere at rt for 3 h. The reaction mixture was then filtered and concentrated to afford tert-butyl (2-(5-((2S,5R)-6-hydroxy-7-oxo-1,6-diazabicyclo[3.2.1]octan-2-yl)-1,3,4-oxadiazol-2-yl)ethyl)carbamate (300 mg, 94%) as a white solid, which was used directly in the next step. ESI-MS (EI+, m/z): 354.24 [M+H]+.
