Participants

Reaction Steps

To a solution of Example 113C (0.43 g, 1.9 mmol) and 2-fluoro-5-sulfamoylbenzoic acid (Enamine, 0.47 g, 2.1 mmol) in THF (10 mL) was added Et3N (0.68 mL, 4.9 mmol) followed by diethyl cyanophosphonate (0.44 mL, 2.9 mmol). The mixture was stirred at ambient temperature for 2 hours then concentrated under reduced pressure. Purification by column chromatography (SiO2, 50% hexanes/EtOAc to 100% EtOAc to 9:1:0.1 EtOAc:MeOH:Et3N) afforded the title compound (0.26 g, 0.62 mmol, 32% yield). MS (DCI/NH3) m/z 423 (M+H)+.
