white crystals | [Uses]
2-Bromo-4-(trifluoromethyl)aniline is mainly used as a raw material for organic synthesis or a reagent for chemical reactions, and can be used to prepare 2-Amino-5-trifluoromethylbenzonitrile and 2-Bromo-1-nitro-4-(trifluoromethyl) benzene among other organic heterocyclic compounds. | [Synthesis]
2-Bromo-4-(trifluoromethyl)aniline is prepared by reacting 4-(trifluoromethyl)aniline with N-bromosuccinimide in dichloromethane. The following is the reaction procedure:
Add 200 mL of distilled CH2Cl 2 and 4- (trifluoromethyl) aniline (20 g, 124.13 mmol) to a two neck flask. Slowly dropwise N-bromosuccinimide (24.3 g, 136.5 mmol) dissolved in CH2Cl2. When the reaction is complete, extract with CH2Cl2. Purification by column separation (EA: Hx = 1: 4) (yield: 50percent)
