Procedure

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]azetidine-1-carboxylate 37 (0.15 g, 0.34 mml) in methanol (15 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]azetidine-1-carboxylate 38 (0.11 g, 91%) as a colorless foam.
