Participants

Reaction Steps

To a solution of (2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxylic acid 1 (0.23 g, 0.83 mmol) in dry DCM (15 mL) were added morpholin-4-amine 209 (0.13 g, 1.25 mmol), 1-hydroxybenzotriazole (0.19 g, 1.41 mmol), 1-ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.24 g, 1.25 mmol) and 4-dimethylaminopyridine (0.15 g, 1.23 mmol) at room temperature. The reaction mixture was stirred at room temperature overnight and concentrated under vacuum. The residue was purified by column chromatography to give (2S,5R)-6-(benzyloxy)-N-(morpholin-4-yl)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxamide 210 (0.255 g, 85%) as a clear thick oil.
