Participants

Reaction Steps

To a mixture of N-(1-hydroxypropan-2-yl)-4-(8-methoxy-4-oxo-4,5-dihydrothieno[2,3-c]quinolin-9-yl)benzenesulfonamide (140 mg, 0.30 mmol) and triphenylphosphine (160 mg, 0.62 mmol) in DMF/CCl4 (1 mL/3 mL) was added NCS (41 mg, 0.31 mmol) and the reaction mixture was stirred at room temperature for 15 h. The reaction mixture was diluted with water (ca. 20 mL), and extracted with DCM (1×50 mL). The extract was washed with water (2×20 mL), brine (1×10 mL), dried over sodium sulfate, and evaporated under vacuum. The residue was purified by flash chromatography to afford the desired product (100 mg, 74%) as light yellow solid; ESI MS m/z 464 [C21H19ClN2O4S+H]+
