The reaction temperature and time need to be carefully regulated. If the temperature is too high, side reactions may occur, resulting in impure products; if the temperature is too low, the reaction will be slow and take a long time. Usually, the reaction temperature can be placed within a certain range, and the target product can be obtained after several hours of reaction. After the reaction is completed, the impurities are removed by conventional separation and purification methods, such as distillation and recrystallization, to obtain pure 2-chloro-4,6-dimethylpyridine.
Second, the corresponding pyridine derivative is also used as the starting material, and the methyl group is first introduced through a specific group conversion reaction to form the prototype of 4,6-dimethylpyridine.

After the successful introduction of methyl groups, the synthesis of 2-chloro-4,6-dimethylpyridine is completed by the above-mentioned chlorination reaction method.
Third, other heterocyclic compounds are also explored as starting materials, through multi-step reactions, pyridine rings are gradually constructed, and chlorine atoms and methyl groups are introduced at the same time. Although this method is complicated in steps, if it is well designed, it can also effectively synthesize the target product. Between each step of the reaction, proper planning is required to ensure that the product of the previous reaction can be successfully used in the next step of the reaction, and the occurrence of side reactions is minimized as much as possible. During the synthesis process, each step of the product requires detailed identification by suitable analytical methods, such as nuclear magnetic resonance and mass spectrometry, to confirm its structure and purity, so as to ensure the quality of the final synthesized 2-chloro-4,6-dimethylpyridine.
