实验过程

6-Chloro-4′-fluoro-4-(pyridazin-4-yl)biphenyl-3-ol (Preparation 102, 150 mg, 0.50 mmol), 5-chloro-N-(2,4-dimethoxybenzyl)-2,4-difluoro-N-(1,3,4-thiadiazol-2-yl)benzenesulfonamide (Preparation 16, 345 mg, 0.75 mmol), and potassium carbonate (207 mg, 1.50 mmol) were suspended in dimethyl sulfoxide (2 mL). The reaction mixture was stirred for 18 hours at room temperature. Water (50 mL) was added and the suspension was extracted with ethyl acetate (2×50 mL) and dichloromethane (3×50 mL). The organic layers were combined, dried over MgSO4, filtered and evaporated. The residue was purified by semi preparative reverse phase HPLC (solvent A: 0.05% formic acid in acetonitrile; solvent B: 0.05% formic acid in water; flow rate: 15 mL/min; gradient 0 min 5% A, 2.5 min 5% A, 22.5 min 95% A, 32.5 min 95% A then return to initial conditions) to afford the title compound (100 mg, 27%) as a glass.
