Procedure

To a solution of (2S,5R)-6-(benzyloxy)-N-(cyclohexyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxamide 22 (0.24 g, 0.64 mml) in methanol (20 mL) was added 5% Pd/C (0.30 g). The mixture was hydrogenated at 35 psi hydrogen atmosphere at room temperature for 1 h. The catalyst was filtered out through Celite, and the filtrate was evaporated to give (2S,5R)-N-(cyclohexyloxy)-6-hydroxy-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxamide 23 (0.155 g, 85%) as a colorless foam.
