Participants

Reaction Steps

2-Chloro-5-(pyridazin-4-yl)-3′-(trifluoromethyl)biphenyl-4-ol (Preparation 52, 140 mg, 0.4 mmol) was dissolved in DMSO (1 mL) and potassium carbonate (110 mg, 0.8 mmol) was added followed by 5-chloro-N-(2,4-dimethoxybenzyl)-2,4-difluoro-N-(1,3,4-thiadiazol-2-yl)benzenesulfonamide (Preparation 16, 203 mg, 0.44 mmol). The reaction was stirred at room temperature for 18 hours and then partitioned between ethyl acetate (50 mL) and water (40 mL). The ethyl acetate was separated and dried over MgSO4, filtered and evaporated. The residue was chromatographed on silica eluting with a gradient of heptane:ethyl acetate 80:20 to 20:80 to give the title compound (231 mg, 0.30 mmol, 73%) as a white solid.
