Versuchsvorschrift

Thiophosgene (1.62 mL, 21.8 mmol) was added dropwise to a stirred mixture of 2,6-dichloro-4-methoxyaniline (2.00 g, 10.4 mmol) in tetrahydrofuran (25 mL) and saturated aqueous sodium hydrogen carbonate (25 mL) at 0° C. The mixture was stirred at room temperature for 1 h, and extracted with ethyl acetate. The combined organic layer was washed with brine, dried over anhydrous sodium sulfate, filtered and concentrated in vacuo. The residue was washed with n-hexane to give the title compound as a brown solid (2.21 g, 9.44 mmol, 91%).
