(2S,5R)-6-(benzyloxy)-N'-(cyclobutylcarbonyl)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carbohydrazide → (2S,5R)-N'-(cyclobutylcarbonyl)-6-hydroxy-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carbohydrazide

Participants

Reaction Steps

A mixture of (2S,5R)-6-(benzyloxy)-N′-(cyclobutylcarbonyl)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carbohydrazide 200 (0.34 g, 0.91 mmol) and Pd/C (0.12 g) in methanol (20 mL) was hydrogenated at 1 atm at room temperature for 3 h. The mixture was filtered through Celite and concentrated to provide 201 (0.30 g, quant. yield) as a white foam.
