Procedure

To a solution of N-(2-hydroxyethyl)-4-(8-methoxy-4-oxo-4,5-dihydrothieno[2,3-c]quinolin-9-yl)benzenesulfonamide (390 mg, 0.90 mmol) and triethylamine (450 mg, 4.5 mmol) in anhydrous THF (20 mL) was added methane sulfonyl chloride (0.21 mL, 2.7 mmol) and the reaction mixture was stirred for 20 h at room temperature. The resulting precipitate was filtered and the filter cake was washed with THF (50 mL). The filtrate was concentrated and the residue was purified by flash chromatography (silica, ethyl acetate/hexanes gradient) to afford the desired product as a brown solid (250 mg, 55%). 1H NMR (300 MHz, DMSO-d6) δ 11.93 (s, 1H), 8.14 (t, J=11.7 Hz, 1H), 7.95 (d, J=8.4 Hz, 2H), 7.79 (d, J=5.4 Hz, 1H), 7.56 (d, J=9.0 Hz, 1H), 7.53 (d, J=8.4 Hz, 2H), 7.43 (d, J=9.0 Hz, 1H), 5.74 (d, J=5.4 Hz, 1H), 4.24 (t, J=10.5 Hz, 2H), 3.71 (s, 3H), 3.20 (q, J=11.7 Hz, 2H) ESI MS m/z 509 [C21H20N2O7S3+H]+
