Reaction Steps

Thiophosgene (10 g, 87.71 mmol) was dissolved in water and stirred at room temperature for 10 min. 4-Amino-2-trifluoromethyl-benzonitrile was added portionwise at room temperature. The reaction mixture was stirred at room temperature for 2 h. The product was extracted with dichloromethane, and the organic layer was washed with water, brine, dried over sodium sulfate and evaporated to obtain 12 g of product. 1H NMR (CDCl3): δ (ppm) 7.84 (d, 1H), 7.58 (s, 1H), 7.48 (d, 1H).
