(2S,5R)-N-(2-Amino-2-oxoethoxy)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxamide → (2S,5R)-N-(2-Amino-2-oxoethoxy)-6-hydroxy-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxamide

Participants

Reaction Steps

A mixture of (2S,5R)—N-(2-amino-2-oxoethoxy)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxamide 54 (0.11 g, 0.40 mmol) and Pd/C (0.040 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 55 (0.10 g, 98%) as a white solid.
