Reaction Steps

N-(2,4-dimethoxybenzyl)-2,4,5-trifluoro-N-1,2,4-thiadiazol-5-ylbenzenesulfonamide (Preparation 647, 157 mg, 0.353 mmol), 4-chloro-2-{1-[1-(diphenylmethyl)azetidin-3-yl]-1H-pyrazol-5-yl}phenol (Preparation 689, 147 mg, 0.353 mmol) and potassium carbonate (147 mg, 1.06 mmol) were stirred in dimethyl sulphoxide (1.0 ml) for 18 hours. The mixture was partitioned between methyl-t-butyl ether (40 ml) and water (20 ml), the organic layer was dried over anhydrous sodium sulphate, filtered and evaporated to give the title compound as a glass, 270 mg.
