First, it can be formed by halogenation of quinoline derivatives. First, take quinoline containing an appropriate substituent, and make it with brominating reagents, such as N-bromosuccinimide (NBS), under suitable reaction conditions. This reaction requires a suitable solvent, such as dichloromethane, etc., and when the appropriate temperature and catalyst exist, the bromine atom can be accurately substituted in the designated position of the quinoline ring, that is, the 2 position, while retaining the 4 position (trifluoromethyl).
Second, the quinoline ring is constructed by multi-step reaction with a halogen atom and an aromatic hydrocarbon (trifluoromethyl) as the starting material. First, the aromatic hydrocarbon undergoes a nucleophilic substitution reaction with a specific reagent, and the group required to construct the quinoline ring is introduced. Then the cyclization reaction is carried out. Common methods such as intramolecular condensation and other means to form the quinoline parent nucleus, and then according to the reaction process and requirements, the obtained product is further modified to reach the structure of 2-bromo-4- (trifluoromethyl) quinoline.
Third, the reaction is catalyzed by transition metals. For example, using (trifluoromethyl) halogenated aromatics and nitrogen-containing heterocyclic compounds as substrates, coupling reactions occur under the action of transition metal catalysts such as palladium catalysts.
