For example, under basic conditions, nucleophilic reagents such as hydroxyl negative ions can attack the halogen atom to connect to the carbon atom, and replace the halogen atom to form the corresponding alcohol or other derivatives. At the same time, the benzene ring on the benzyl group can undergo typical aromatic ring reactions, such as the Fu-gram reaction. Under the catalysis of Lewis acid, it reacts with acyl halides or halogenated hydrocarbons to introduce new substituents on the benzene ring. In addition, the quinoline ring also has a certain activity, which can be reduced and oxidized. For example, under the action of suitable reducing agents, the quinoline ring can be partially or completely hydrogenated to generate products with different degrees of hydrogenation.

The synthesis method of 3-benzyl-6-bromo-2-chloroquinoline follows the classical path of organic synthesis. The first method is to start with a compound containing quinoline parent nuclei, and introduce bromine and chlorine atoms by halogenation reaction. First, the quinoline is substituted at a specific position with appropriate halogenating reagents, such as brominating agents and chlorinating agents, under suitable reaction conditions. During bromination, the quinoline ring electron cloud distribution and reactivity, the appropriate bromine source, such as liquid bromine or N-bromosuccinimide (NBS), is selected. Under the catalysis of catalysts such as Lewis acid, bromine atoms are introduced at the 6th position at a specific temperature and time. Then the chlorination step, select a suitable chlorinating agent, such as phosphorus oxychloride or sulfoxide dichloride, and introduce chlorine atoms at the second position through a similar reaction process. Finally, through the benzylation reaction, the benzyl halide, such as benzyl bromide, is used under the catalysis of the base, so that the benzyl group is connected to the quinoline 3 position, and then the target product is obtained.
Its synthesis method 2 can start from the construction of quinoline ring. The quinoline parent nucleus is constructed by condensation reaction with aromatic amine and aromatic aldehyde as starting materials. The nucleophilic addition-elimination reaction of shilling aromatic amine and aromatic aldehyde is carried out under the catalysis of acid or base to form an intermediate product. Following the above halogenation and benzylation steps, bromine, chlorine and benzyl groups are introduced in sequence to achieve the synthesis of 3-benzyl-6-bromo-2-chloroquinoline.
During the synthesis, the reaction conditions of each step should be carefully observed. Temperature, reaction time, proportion of reactants, type and dosage of catalysts all have a profound impact on the reaction yield and selectivity. If the halogenation reaction is too high or too low, the non-side reaction will increase, that is, the reaction rate will be slow and the yield will not be good. And the choice of reaction solvent is also critical. Polar or non-polar solvents should be selected according to the reaction characteristics of each step to facilitate the smooth progress of the reaction. Purification steps can not be ignored, commonly used column chromatography, recrystallization and other methods to obtain high purity of the target product.
