실험 절차

To a solution of 3-cyano-N-(2,4-dimethoxybenzyl)-4-fluoro-N-1,2,4-thiadiazol-5-ylbenzenesulfonamide (Preparation 19, 206 mg, 0.474 mmol) and 3-pyridazin-4-yl-3′-(trifluoromethyl)biphenyl-4-ol (Preparation 3, 150 mg, 0.474 mmol) in dimethylsulfoxide (5 mL) was added potassium carbonate (196 mg, 1.42 mmol). The reaction mixture was stirred at room temperature for 18 hours. The reaction mixture was quenched with a 1M aqueous solution of sodium hydroxide whereupon a fine precipitate formed. The mixture was extracted with ethyl acetate. The organic layer was separated, dried over anhydrous magnesium sulfate, filtered and concentrated in vacuo to afford the title compound as an oil (380 mg, 111%, contains residual dimethylsulfoxide). The material was used without purification in the next step.
