First, a suitable pyridine derivative is used as the starting material. Through a halogenation reaction, bromine atoms are introduced. If pyridine is used as the initial product, under specific reaction conditions, such as selecting a suitable halogenating reagent, such as bromine (Br ²), and matching with a suitable catalyst, such as iron powder (Fe) or iron tribromide (FeBr < unk >), at a suitable temperature and reaction time, a specific position on the pyridine ring can be brominated to obtain a bromine-containing pyridine derivative. Then, by constructing the diazole ring structure.

In the preparation of 4,7-dichloro- [1,2,5] -diazolo [3,4-c] pyridine, the following things should be paid attention to:
First, the purity of the raw material is very important. In order to obtain high-purity 4,7-dichloro- [1,2,5] -diazolo [3,4-c] pyridine, the raw materials used must have high purity. If the raw material contains impurities, the purity of the product will be reduced during the reaction or by-reactions, and the separation and purification will also be more difficult. Therefore, before taking the raw material, it is necessary to check its purity carefully. If it does not meet the standard, purify it first.
Second, the control of the reaction conditions must be accurate. Factors such as temperature, pH and reaction time all have a profound impact on the reaction. If the temperature is too high or too low, the reaction rate or product selectivity are affected. If the reaction temperature is too high, or the side reactions are intensified, the product yield will decrease; if the temperature is too low, the reaction rate will be slow and time-consuming. The pH cannot be ignored. Appropriate pH can promote the reaction, or inhibit the reaction. Furthermore, the reaction time needs to be strictly controlled. If it is too short, the reaction will not be completed, and if it is too long, it may cause the product to decompose.
Third, the choice of solvent is very important. Different solvents have different effects on the solubility and reactivity of the reactants. When choosing a solvent, it is necessary to consider its solubility to the reactants, and it should be able to fully dissolve the reactants to ensure that the reaction proceeds uniformly. At the same time, the solvent cannot have adverse reactions with the reactants or products, and it is convenient for the separation and purification of the products.
Fourth, safety protection should not be slack. The reagents used in the preparation process may be toxic, corrosive or flammable. Operators must wear appropriate protective equipment, such as protective clothing, gloves and goggles, to prevent physical damage caused by contact with reagents. And the experimental site should be well ventilated, and harmful gases should be discharged in time. At the same time, waste should be properly disposed of to prevent environmental pollution.
Fifth, monitoring and controlling the reaction process is indispensable. By means of thin layer chromatography, high performance liquid chromatography and other analytical methods, the reaction process can be monitored in real time to gain insight into the degree of reaction progress and product generation. According to the monitoring results, adjust the reaction conditions in a timely manner to ensure that the reaction proceeds in the expected direction to obtain the ideal product yield and purity.
