Procedure

5-Chloro-N-(2,4-dimethoxybenzyl)-2-fluoro-4-{[3-pyridazin-4-yl-2′-(trifluoromethyl)biphenyl-4-yl]oxy}-N-1,3,4-thiadiazol-2-ylbenzenesulfonamide (Preparation 23, 339 mg, 0.45 mmol) was dissolved in a 4M solution of hydrogen chloride in 1,4-dioxane (10 mL). The mixture was stirred at room temperature for 2 hours. The reaction mixture was concentrated in vacuo and the resulting residue purified by reverse phase preparative HPLC (Trilution method) to afford the title compound as a white solid (75 mg, 27%).
