Procedure

To a solution of (2R,5S)-6-(benzyloxy)-N′-(2-methylpropanoyl)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carbohydrazide 194 (0.30 g, 0.83 mml) in methanol (20 mL) was added 5% Pd/C (0.40 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-N′-(2-methylpropanoyl)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carbohydrazide 195 (0.21 g, 95%) as a colorless foam.
