Procedure

3-cyano-4-[2-(5-methyl-1-trityl-1H-pyrazol-4-yl)-4-(trifluoromethyl)phenoxy]-N-1,2,4-thiadiazol-5-ylbenzenesulfonamide (Preparation 428, 345 mg, 0.46 mmol) was dissolved in 4N HCl in 1,4-dioxane (5 ml) and stirred at room temperature for 3 hours before concentrating in vacuo. The residue obtained was purified using an ISCO™ (12 g SiO2) eluting with methanol:dichloromethane (gradient 0:1 to 1:9, by volume). The purified compound was triturated with dichloromethane (10 mL) to afford the title compound as a white solid (148 mg, 34%—isolated as the hydrochloride salt).
