If the cap temperature is too high, it is easy to cause side reactions and the product is impure. Improper time, or the reaction is not completed, or excessive reaction is not conducive to the formation of the target product. Then, 3-nitropyridine is chlorinated again. A suitable chlorination reagent, such as phosphorus oxychloride, can be selected. In this reaction, attention should also be paid to the reaction environment to ensure that the reaction proceeds smoothly to obtain 4-chloro-3-nitropyridine.

Third, it can be synthesized by the reaction of transition metal catalysis. Using a substrate containing a pyridine ring, with the help of the unique properties of transition metal catalysts, chlorine atoms and nitro groups can be precisely integrated into the specific position of the pyridine ring. This method requires strict reaction conditions. The selection of catalysts, the collocation of ligands, and the screening of reaction solvents all affect the success or failure of the reaction and the yield and purity of the product. The purpose of high-efficiency synthesis of 4-chloro-3-nitropyridine can only be achieved through careful experimental exploration and optimization of various reaction parameters.
