Reaktionsschritte

To a solution of 2-iodophenol (6.0 mmol, 1320 mg) and K2CO3 (10.5 mmol, 1450 mg) in DMF (15.0 mL) was added 3-cyano-4-fluoro-N-(1,2,4-thiadiazol-5-yl)benzenesulfonamide (Preparation 65, 4.5 mmol, 1280 mg). The reaction mixture was heated at 80° C. for 24 hours. The reaction was cooled to room temperature and the mixture was poured into 1 N aqueous HCl (100 mL) to obtain a white solid. The afforded solid was washed with heptane and the solid was dried in vacuo to furnish 1.932 g of the title compound. LCMS Rt=1.67 minutes MS m/z 485 [MH]+
