Versuchsvorschrift

To a solution of 6-methoxy-2-(trifluoromethyl)pyridin-3-amine (6.99 g, 36.4 mmol) in tetrahydrofuran (60 mL) and saturated aqueous sodium hydrogen carbonate (60 mL) was added dropwise thiophosgene (2.8 mL, 36.5 mmol) at 0° C. The mixture was stirred at 0° C. for 0.5 hr. Water was added to the reaction mixture and the mixture was extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous magnesium sulfate, and concentrated in vacuo to give the title compound (8.49 g, 36.3 mmol, quant.) as a pale orange oil.
