Procedure

To a solution of (2R,5S)-6-(benzyloxy)-7-oxo-N′-(3,3,3-trifluoropropanoyl)-1,6-diazabicyclo[3.2.1]octane-2-carbohydrazide 229 (0.26 g, 0.65 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,5S)-6-hydroxy-7-oxo-N′-(3,3,3-trifluoropropanoyl)-1,6-diazabicyclo[3.2.1]octane-2-carbohydrazide 230 (0.19 g, 93.6%) as a colorless foam.
