Versuchsvorschrift

A mixture of di-tert-butyl[{4-[({[(2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]oct-2-yl]carbonyl}amino)oxy]piperidin-1-yl}methylylidene]biscarbamate 66 (0.26 g, 0.42 mmol) and Pd/C (0.080 g) in methanol (10 mL) was hydrogenated at 1 atm at room temperature for 3 h. The mixture was filtered through Celite pad and concentrated to provide 67 (0.21 g, 98%) as a white solid.
