Reaction Steps

To a solution of (2S,5R)-6-(phenylmethoxy)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxylic acid (38.9 mg, 0.141 mmol) in dry dichloromethane (2 mL) was added triethylamine (0.049 mL, 0.352 mmol), 2-chloro-1-methylpyridinium iodide (53.3 mg, 0.209 mmol), and 2-methoxy-4-aminopyridine (20.2 mg, 0.163 mmol) sequentially at room temperature under nitrogen. The reaction was then heated to 50° C. for 1.5 hours. LC/MS showed reaction complete. The reaction mixture was concentrated and purified by HPLC on a 30×100 mm Waters Sunfire column to afford the title compound as an orange solid after lyophilization.
