Procedure

A mixture of (2S,5R)-6-(benzyloxy)-7-oxo-N′-propanoyl-1,6-diazabicyclo[3.2.1]octane-2-carbohydrazide 203 (0.31 g, 0.89 mmol) and Pd/C (0.12 g) in methanol (20 mL) was hydrogenated at 1 atm at room temperature for 16 h. The mixture was filtered through Celite and concentrated to provide 204 (0.24 g, quant. yield) as a white foam.
