To a solution of N-(4-fluoro-3-(quinoxaline-6-carbonyl)phenyl)-N-(propylsulfonyl)propane-1-sulfonamide (50 mg, 0.10 mmol, 1.0 eq.) in MeOH (10 mL) was added NaOH aqueous solution (1 N, 0.22 mL, 0.22 mmol, 2.2 eq.). The resulting mixture was stirred at it for 1 h, then concentrated. The resulting residue was purified by flash column chromatography (PE/EA=1/1, v/v) to afford N-(4-fluoro-3-(quinoxaline-6-carbonyl)phenyl)propane-1-sulfonamide (33.4 mg, 89.5%). LRMS (M+H+) m/z calculated 374.1, found 374.1. 1H NMR (CDCl3, 400 MHz) δ 8.94-8.97 (dd, 2 H), 8.46-8.47 (m, 1 H), 8.31-8.34 (m, 1 H), 8.23-8.25 (m, 1 H), 7.50-7.54 (m, 1 H), 7.46-7.48 (m, 1 H), 7.19-7.23 (t, 1 H), 6.80 (s, 1 H), 3.10-3.14 (m, 2 H), 1.86-1.92 (m, 2 H), 1.04-1.08 (t, 3 H).
