Reaction Steps

To a solution of tert-butyl 3-[({[(2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]oct-2-yl]carbonyl}amino)oxy]-8-azabicyclo[3.2.1]octane-8-carboxylate 46 (0.26 g, 0.52 mml) in methanol (20 mL) was added 5% Pd/C (0.3 g). The mixture was hydrogenated under 35 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 3-[({[(2S,5R)-6-hydroxy-7-oxo-1,6-diazabicyclo[3.2.1]oct-2-yl]carbonyl}amino)oxy]-8-azabicyclo[3.2.1]octane-8-carboxylate 47 (0.14 g, 66%) as a white solid.
