Procedure

To a solution of tert-butyl[({[(2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]oct-2-yl]carbonyl}amino)oxy]acetate 89 (0.23 g, 0.57 mml) in methanol (20 mL) was added 5% Pd/C (0.30 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[({[(2S,5R)-6-hydroxy-7-oxo-1,6-diazabicyclo[3.2.1]oct-2-yl]carbonyl}amino)oxy]acetate 90 (0.16 g. 89%) as a clear thick oil.
