To a solution of (2R,5S)-6-(benzyloxy)-N′-[(dimethylamino)acetyl]-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carbohydrazide 241 (0.15 g, 0.40 mml) in methanol (20 mL) was added 5% Pd/C (0.20 g). The mixture was hydrogenated under 10 psi hydrogen atmosphere at room temperature for 1 h. The catalyst was filtered out through Celite and the filtrate was evaporated to give (2R,5S)—N′-[(dimethylamino)acetyl]-6-hydroxy-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carbohydrazide 242 (0.10 g, 88%) as a white foam.
