The synthesis of methyl-3-amino-5,6-dichloropyrazine-2-carboxylic acid esters is involved in the field of organic synthesis. The synthesis of this compound is often done by a numerical method.
First, 5,6-dichloropyrazine-2-carboxylic acid is used as the starting material. The carboxylic acid is heated with thionyl chloride, and the carboxyl group of the carboxylic acid can be converted into an acid chloride. Sulfuryl chloride is strongly chlorinated and reacts with carboxylic acid to form acid chloride, sulfur dioxide and hydrogen chloride. The reaction conditions are mild and the yield is good. The obtained acid chloride reacts with methanol and ammonia under suitable conditions. Methanol and acyl chloride react to form methyl esters, and ammonia sources aminize them to obtain methyl-3-amino-5,6-dichloropyrazine-2-carboxylic acid esters. The ammonia source can be selected as an alcohol solution of ammonia gas or an organic amine, depending on the actual situation and needs.
Second, start from pyrazine derivatives containing appropriate substituents. If there are pyrazine compounds containing suitable substituents and can be converted to target amino groups and methyl ester groups, they can be achieved through multi-step reactions. For example, a pyrazine derivative is first introduced into chlorine atoms at positions 5,6 through halogenation. The halogenating agent can be selected from chlorine gas, thionyl chloride, etc., according to the reaction conditions and substrate activity. After the conversion of functional groups, a functional group is converted into carboxyl groups, and then esterification and amination reactions can be carried out to obtain the target product. The esterification can be reacted with methanol under acid catalysis, and the amination depends on the selected ammonia source and reaction conditions.
During the synthesis process, each step of the reaction needs to be controlled by temperature, time and appropriate solvent selection. Temperature and time have a great influence on the reaction process and yield. The choice of solvent is related to the reaction rate, selectivity and product purity. And after each step of the reaction, it needs to be separated and purified, such as column chromatography, recrystallization, etc., to remove impurities to obtain pure methyl-3-amino-5,6-dichloropyrazine-2-carboxylic acid ester.

Methyl 3-amino-5,6-dichloropyrazine-2-carboxylic acid ester, an important organic compound in the field of fine chemicals, is widely used in medicine, pesticides and other industries. As for its market price, it is difficult to sum up, because it is deeply influenced by many factors.
First, the cost of raw materials has a significant impact. If the price of the starting materials required for the preparation of this compound, such as specific halogens, amines, etc., fluctuates frequently, the cost of the product and the market price will fluctuate. If the supply of raw materials is tight and the price soars, the price of the finished product will also rise; conversely, the supply of raw materials is abundant, the price is stable, and the price of the product is expected to stabilize.
Second, the complexity and cost of the production process are significant. If the process is advanced, the production efficiency is high, the energy consumption and waste output are small, and the cost may be reduced, the market price will be competitive; however, the process is complex, the technical requirements are high, and the equipment investment and production costs increase greatly, so the price will naturally rise.
Third, the market supply and demand situation is a key factor. If the downstream industries such as pharmaceuticals and pesticides have strong demand for this compound, but the supply is limited, the price will be upward; if the market supply exceeds the demand, the enterprise may sell it for promotion, or the price will be reduced.
Fourth, the macroeconomic environment, policies and regulations also play a role. The economic situation is good, the industry is developing well, and the price may be relatively stable. Stringent environmental protection policies, increased environmental protection investment by enterprises, and rising costs will also affect the price.
According to past market conditions, the price of this compound may range from tens of thousands to hundreds of thousands of yuan per ton due to the above factors. However, the market is changing rapidly. If you want to know the accurate market price, you need to pay attention to the market dynamics of chemical raw materials in real time and consult relevant manufacturers or distributors.

Methyl-3-amino-5,6-dichloropyrazine-2-carboxylic acid ester is one of the organic compounds. Its storage conditions are crucial to the stability and quality of this compound.
This compound should be stored in a cool and dry place. Because the temperature is too high, it is easy to cause chemical reactions, structural changes, and loss of original properties; and excessive humidity may cause the compound to absorb moisture, triggering reactions such as hydrolysis, which also damages its quality.
