Procedure
A solution of 5-(ethylsulfonyl)-2-methoxyaniline (15.6 g, 72.5 mmol) in dichloromethane (100 mL) was added dropwise over 1 h to a stirred solution of thiophosgene (9 g, 78.0 mmol) in dichloromethane (300 mL) at RT. After the addition was complete, the reaction was stirred for 2 h. Subsequently, saturated aqueous sodium bicarbonate (200 mL) was added, and the reaction was stirred for an additional 1 h. The organic layer was separated, and the aqueous layer was extracted with dichloromethane (2×100 mL). The combined organic layers were dried over anhydrous magnesium sulfate, filtered, and concentrated under reduced pressure to afford the title compound (18.6 g, 72.4 mmol) as a tan solid. 1H NMR (400 MHz, d6-DMSO): δ 7.78 (dd, J1=2.2, J2=8.8, 1H), 7.71 (d, J=2.2, 1H), 7.35 (d, J=8.8, 1H), 3.95 (s, 3H), 3.22 (q, J=7.4, 2H), 1.02 (t, J=7.3, 3H).
