A solution of 4-chloro-N-[5-chloro-2-(3-oxo-1,3-dihydro-isobenzofuran-1-yl)-pyridin-3-yl]-N-methoxymethyl-3-trifluoromethyl-benzenesulfonamide in 3 mL HCl (4 M in dioxane) and 1 mL water was refluxed for 2 h. After cooling to room temperature, the mixture was concentrated and the residue was purified via preparative TLC (50% EtOAc in hexane) to provide 11 mg of 4-chloro-N-[5-chloro-2-(3-oxo-1,3-dihydro-isobenzofuran-1-yl)-pyridin-3-yl]-3-trifluoromethyl-benzenesulfonamide as an off white solid.
