Procedure

To a stirred solution of 2-chloro-4-methoxyaniline (7.90 g, 50.1 mmol) in saturated aqueous sodium hydrogen carbonate (40 mL) and tetrahydrofuran (40 mL) was added thiophosgene (4.99 mL, 65.1 mmol) at room temperature. After 30 min, the reaction mixture was extracted with ethyl acetate, washed with aqueous sodium hydrogen carbonate and brine, dried over sodium sulfate, filtrated, and concentrated in vacuo. The resulting solid was washed with n-hexane to give the title compound as a pale red solid (6.85 g, 34.3 mmol, 68%).
