Reaction Steps

100 g of iron fillings are heated to 95° C. in 300 ml of water, 5 ml of hydrochloric acid and 5 ml of dioxane in a stirred vessel, and 57 g of 2-nitro-5-methylbenzotrifluoride are added dropwise in the course of about 1 hour. The mixture is stirred for a further 2 hours, and a distillation is then carried out using steam. The organic material extracted with dichloromethane and re-distilled. 42 g (boiling point: 92°-95° C./20 mbar) of 2-trifluoromethyl-4-methylaniline are obtained.
