Procedure

To a solution of tert-butyl 2-{[({[(2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]oct-2-yl]carbonyl}amino)oxy]methyl}-1,4-oxazepane-4-carboxylate 132 (0.32 g, 0.63 mml) in methanol (20 mL) was added 5% Pd/C (0.30 g). The mixture was hydrogenated at 15 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 2-{[({[(2S,5R)-6-hydroxy-7-oxo-1,6-diazabicyclo[3.2.1]oct-2-yl]carbonyl}amino)oxy]methyl}-1,4-oxazepane-4-carboxylate 133 (0.205 g, 78%) as a colorless foam.
