Procedure

A mixture 4-chloro-N-{5-chloro-2-[2-(methanesulfonyl-methyl-amino)-benzoyl]-pyridin-3-yl}-N-methoxymethyl-3-trifluoromethyl-benzenesulfonamide (30 mg crude) in 4 M HCl in dioxane (12 mL) and water (4 mL) were heated at 100° C. for 18 h. The reaction mixture was concentrated to dryness under reduced pressure and subsequently neutralized aqueous NaHCO3 to pH to 5-6. The aqueous layer was extracted with EtOAc, the combined extracts were dried (Na2SO4), filtered, and concentrated under reduced pressure. The residue was purified by preparative HPLC (20→80% gradient of MeCN-water) to provide 4-chloro-N-{5-chloro-2-[2-(methanesulfonyl-methyl-amino)-benzoyl]-pyridin-3-yl}-3-trifluoromethyl-benzenesulfonamide as a solid. MS m/z: 582.0 (M+H).
