The method mostly uses compounds containing quinoline structure as starting materials, and the required bromine, chlorine and carboxylethyl ester groups are introduced according to specific reaction steps.
Common starting materials are either quinoline itself or quinoline derivatives with specific substituents. First, under specific reaction conditions, bromine and chlorine atoms are selectively introduced into the designated positions of the quinoline ring. The commonly used brominating agents include liquid bromine, N-bromosuccinimide (NBS), etc.; the chlorinating agents are thionyl chloride, phosphorus trichloride, etc. During the reaction, the reaction temperature, time and the proportion of reactants need to be precisely controlled to achieve the ideal substitution position and yield.
After the halogenation step is completed, the carboxyl ethyl ester group is introduced. This step may be formed by reacting carboxyl-containing compounds with ethanol under the action of esterification reagents. Commonly used esterification reagents, such as concentrated sulfuric acid, dicyclohexyl carbodiimide (DCC), etc. Or carboxyl groups are introduced first, and then esterified to form ethyl ester groups. In the reaction process, the choice of solvent is also the key. Commonly used organic solvents, such as dichloromethane, N, N-dimethylformamide (DMF), need to be selected according to the reaction characteristics of each step to facilitate the smooth progress of the reaction.
After each step of the reaction, it must be separated and purified, such as column chromatography, recrystallization, etc., to remove impurities and obtain a pure product. Fine regulation of the reaction conditions at each step and proper treatment of intermediates are the keys to the successful synthesis of ethyl 6-bromo-4-chloroquinoline-3-carboxylate.
