Reaction Steps

To a solution of (2S,5R)-6-(phenylmethoxy)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxylic acid (53 mg, 0.192 mmol) in dry dichloromethane (2 mL) was added a solution of tert-butyl (3R)-3-aminopyrrolidine-1-carboxylate (55 mg, 0.288 mmol), triethylamine (0.061 mL, 0.441 mmol), HOBT (44.1 mg, 0.288 mmol), and EDC (55.2 mg, 0.288 mmol) sequentially at room temperature under nitrogen. The reaction was stirred at room temperature for six hours. The reaction mixture was 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.
