Versuchsvorschrift

Iodine monochloride (17.2 g, 108 mmol) in hydrochloric acid (36%, 21.4 g) and water (35 mL) was added dropwise to 2-chloro-4-(trifluoromethyl)benzenamine (20.0 g, 102 mmol) in hydrochloric acid (36%, 20.7 g) and water (140 mL). The mixture was warmed to 50° C. for a total of 8 h. Sodium hydroxide (50%, 33.5 g, 419 mmol) was added to the mixture at room temperature. The mixture was extracted with dichloromethane (2×250 mL), and the extracts were dried and evaporated to give the product as an oil (31.83 g, 97% yield).
