실험 절차

To a solution of 3-cyano-N-(2,4-dimethoxybenzyl)-4-fluoro-N-1,2,4-thiadiazol-5-ylbenzenesulfonamide (Preparation 68, 25 g, 57.5 mmol) in DMSO (125 mL) was added potassium carbonate (20.4 g, 148 mmol) followed by dropwise addition of the 2-iodo-4-(trifluoromethyl)phenol (Preparation 224, 17.4 g, 60.6 mmol). The reaction was stirred at room temperature for 2 hours. The reaction was poured into water (1 L) and extracted with ethyl acetate (3×300 mL). The organic layers were combined and washed with water (2×250 mL), dried over sodium sulfate and concentrated in vacuo. The residue was slurried in methanol (150 mL) for 1 hour before filtering and drying under vacuum to afford 33.92 g of the title compound as a white solid (83%).
