YieldReaction ConditionsOperation in experiment
In water; Example 1 Preparation of 2,4,5-trifluoroaniline 300 parts of dimethyl acetamide was stirred at 5°C and 148 parts of 3-amino-2,5,6-trifluorobenzoic acid was added. The temperature was raised to 150°C, when CO2 was evolved, and the temperature maintained at 150°C for 1 [1/2 ] hours. The reaction mixture was distilled up to 190°C and the distillates drowned into 1500 parts of water with stirring. The white solid was filtered off, washed with water and dried to give 46 parts of product. The aqueous dimethyl acetamide was extracted with 2 x 500 parts of CH2Cl2 which in turn was washed with 3 x 250 parts of water. The CH2Cl2 solution as dried and evaporated to give 21 parts of solid. A total of 67 parts (60percent) of 2,4,5-trifluoroaniline was obtained.
