(2R,5S)-N'-acetyl-6-(benzyloxy)-N'-methyl-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carbohydrazide → (2R,5S)-N'-acetyl-6-hydroxy-N'-methyl-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carbohydrazide

Participants

Reaction Steps

To a solution of (2R,5S)-N′-acetyl-6-(benzyloxy)-N′-methyl-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carbohydrazide 213 (0.20 g, 0.57 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)-N′-acetyl-6-hydroxy-N′-methyl-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carbohydrazide 214 (0.15 g, 99%) as a colorless foam.
