実験手順

5-Chloro-4-(6-chloro-4′-fluoro-4-(pyridazin-4-yl)biphenyl-3-yloxy)-N-(2,4-dimethoxybenzyl)-2-fluoro-N-(1,3,4-thiadiazol-2-yl)benzenesulfonamide (Preparation 101, 100 mg, 0.13 mmol) was dissolved in a 4M solution of HCl in dioxane (10 mL). The reaction mixture was stirred for 18 hours at room temperature. Methanol (50 mL) was added to the reaction mixture and the suspension was concentrated in vacuo. The crude residue was purified by reverse phase semi preparative HPLC (solvent A: 0.05% formic acid in acetonitrile, solvent B: 0.05% formic acid in water; flow rate: 12.5 ml/min; gradient: 0 min 10% A, 2.5 min 10% A, 32.5 min 95% A, 37.5 min 95% A then return to initial conditions) to afford the title compound (46 mg, 60%) as a solid.
