Procedure

To a vial containing Ethyl 5-(3-(4-chloro-3-(trifluoromethyl)benzenesulfonamido)-5-chloropyridin-2-yl)-4-isopropyl-4H-1,2,4-triazole-3-carboxylate (59 mg, 0.1 mmol) was added THF (0.6 mL) and NH4OH (0.2 mL). The solution was stirred at room temperature for 16 h. EtOAc (30 mL) was added. The organic phase washed with water (2×10 mL) and dried over Na2SO4. The volatiles were removed in vacuo. The resulting residue was purified by preparative HPLC (20→95% gradient of MeCN—H2O with 0.1% TFA) and the pure fractions lyophilized to afford the title compound (4.0 mg, 8% yield). HPLC retention time=2.76 minutes. 1H NMR (400 MHz, CDCl3) δ 8.41 (d, J=2.0, 1H), 8.16 (d, J=2.0, 1H), 8.05 (d, J=2.4, 1H), 7.85 (dd, J=2.4, 8.4, 1H), 7.53 (d, J=8.4, 1H), 5.75 (sept, J=6.8, 1H), 1.52 (d, J=6.8, 6H). MS (ES) [M+H]+ expected 523.0. found 522.9.
