Reaction Steps

To a solution of tert-butyl (2S)-2-[(2-{[(2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]oct-2-yl]carbonyl}hydrazinyl)carbonyl]piperidine-1-carboxylate 271 (0.37 g, 0.74 mml) in methanol (25 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 tert-butyl (2S)-2-[(2-{[(2S,5R)-6-hydroxy-7-oxo-1,6-diazabicyclo[3.2.1]oct-2-yl]carbonyl}hydrazinyl)carbonyl]piperidine-1-carboxylate 272 (0.29 g, 96%) as a white foam.
