Reaction Steps

To a solution of (2S,5R)-6-(phenylmethoxy)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxylic acid (1 g, 3.62 mmol) in dry dichloromethane (30 mL) was added dimethylaminopyridine (884 mgL, 7.24 mmol), EDC (1.388 g, 7.24 mmol), and tert-butyl (3S)-3-aminopyrrolidine-1-carboxylate (742 mg, 3.98 mmol) sequentially at room temperature under nitrogen. The reaction mixture was stirred at room temperature over the weekend. The reaction mixture was then concentrated under vacuum and the residue was purified by HPLC on a 30×100 mm Waters Sunfire column eluted with 15% to 100% CH3CN+0.05% TFA/water+0.05% TFA over 15 minutes to afford the title compound as a white solid.
