Procedure

To a solution of (2R,5R)-6-(benzyloxy)-7-oxo-N′-(trifluoroacetyl)-1,6-diazabicyclo[3.2.1]octane-2-carbohydrazide 185 (0.224 g, 0.58 mml) in methanol (20 mL) was added 5% Pd/C (0.30 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,5R)-6-hydroxy-7-oxo-N′-(trifluoroacetyl)-1,6-diazabicyclo[3.2.1]octane-2-carbohydrazide 186 (0.15 g, 88%) as a colorless foam.
