Reaction Steps

To a N-(3-(3-(4-chlorophenyl)quinoxaline-6-carbonyl)-2,4,5-trifluorophenyl)-N-(propylsulfonyl)propane-1-sulfonamide (50 mg, 0.08 mmol, 1.0 eq.) in MeOH (5 mL) was added NaOH aqueous solution (1 N, 0.16 mL, 0.16 mmol, 2.0 eq.). The resulting mixture was stirred at rt for 1 h, then concentrated. The resulting residue was purified by flash column chromatography (PE/EA=2/1, v/v) to afford N-(3-(3-(4-chlorophenyl)quinoxaline-6-carbonyl)-2,4,5-trifluorophenyl)propane-1-sulfonamide (25 mg, 60.2%). LRMS (M−H+) m/z calculated 518.1, found 518.0. 1H NMR (CDCl3, 400 MHz) δ 9.42 s), 8.44 (s, 1 H), 8.27-8.38 (m, 2 H), 8.14-8.16 (dd, 2 H), 7.73-7.76 (m, 1 H), 7.55-7.57 (dd, 2 H), 6.55 (s, 1 H), 3.14-3.18 (m, 2 H), 1.88-1.94 (q, 2 H), 1.06-1.10 (t, 3 H).
