Reaction Steps

4-Chloro-N-[5-chloro-2-(hydroxy-pyridin-4-yl-methyl)-pyridin-3-yl]-N-methoxymethyl-3-trifluoromethyl-benzenesulfonamide (30 mg, 0.06 mmol) in 50% aqueous of MeOH (10 mL) was treated with 5-10 drops of conc. HCl and heated at 80° C. for 3 days. The resulting mixture was cooled to room temperature, concentrated under reduced pressure and neutralized with aqueous NaHCO3 to pH 7. It was then extracted with EtOAc to provide crude 4-chloro-N-[5-chloro-2-(hydroxy-pyridin-4-yl-methyl)-pyridin-3-yl]-3-trifluoromethyl-benzenesulfonamide which was purified by preparative HPLC. 1H NMR (400 MHz, CDCl3) δ 8.34 (br, 2 H), 8.29 (d, J=2.0 Hz, 1 H), 7.97 (s, 1 H), 7.91 (s, 1 H), 7.44 (d, J=8.4 Hz, 1 H), 7.38 (d, J=8.4 Hz, 1 H), 7.11 (d, J=5.6 Hz, 2 H), 5.98 (s, 1 H); MS m/z: 478.0 (M+H).
