実験手順

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-2′-(trifluoromethyl)biphenyl-4-ol (Preparation 9, 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 precipitate formed. The precipitate was collected by filtration and washed with water to afford the title compound as a solid (400 mg, 115%, contains residual dimethylsulfoxide). The material was used without purification in the next step.
