A mixture of tert-butyl {(2S)-1-[({[(2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]oct-2-yl]carbonyl}amino)oxy]propan-2-yl}carbamate 60 (0.237 g, 0.528 mmol) and Pd/C (0.200 g) in methanol (20 mL) was hydrogenated at 35 psi at room temperature for 2 h. The mixture was filtered through a Celite pad and concentrated to provide 61 (crude, 0.189 g, quant.) as a colorless foam which was used in the next step without purification.
