Reaction Steps

Intermediate 104A (145 mg, 0.234 mmol) was dissolved in MeOH (2.2 mL) and then 1 N NaOH (0.2 mL) was added. The mixture was stirred at 69° C. for 45 min and added another 0.2 mL of 1 N NaOH. The reaction was heated at 130° C. under microwave conditions for 10 min. The mixture was neutralized with 1 N HCl and then concentrated. The residue was purified by silica gel chromatography (12 g silica gel, eluted with EtOAc in hexanes) to yield the desired product (80 mg, 57%). LCMS Anal. Calc'd for C31H24F6N2O4 602.16, found [M+H] 603.3.
