To a solution of 5-((2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]octan-2-yl)-1,2,4-oxadiazole-3-carboxamide (220 mg, 0.641 mmol) in MeOH (4.0 mL) and THF (12.0 mL) was added 10% Pd/C (13.6 mg, 0.013 mmol). The reaction mixture was stirred under hydrogen balloon for 1 h at rt, then filtered and concentrated to afford 5-((2S,5R)-6-hydroxy-7-oxo-1,6-diazabicyclo[3.2.1]octan-2-yl)-1,2,4-oxadiazole-3-carboxamide (˜150 mg, 93%), which was used directly in the next step.
