Reaction Steps

To a solution of (2S,5R)-6-(phenylmethoxy)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxylic acid (0.400 g, 1.448 mmol) in dry dichloromethane (17.66 mL) was added triethylamine (0.504 ml, 3.62 mmol), 2-chloro-1-methylpyridinium iodide (0.433 g, 1.694 mmol), and 2-amino-5-bromopyridine (0.311 g, 1.795 mmol) sequentially at room temperature under nitrogen. The reaction mixture was heated to 50° C. for 1 hour then purified on the mass directed HPLC (30×100 mm Waters Sunfire column; 5 micron; 50 ml/min; acetonitrile/water with 0.1% TFA over 15 min). Fractions containing the title compound were concentrated under vacuum then lyophilized overnight to afford the title compound as a yellow solid.
