The synthesis methods of 2-chloro-3-methoxypyrazine have existed in ancient times, and there are many kinds. The following are briefly described several common methods.
First, pyrazine is used as the initial raw material. First, pyrazine interacts with chlorinated reagents, such as thionyl chloride, phosphorus oxychloride, etc. Under specific conditions, such as in a suitable solvent, such as dichloromethane, chloroform, controlled at a certain temperature, or at room temperature, or heated, a substitution reaction occurs, so that chlorine atoms are introduced into a specific position on the pyrazine ring to generate 2-chloropyrazine. Subsequently, 2-chloropyrazine and methoxylating reagents, such as sodium methoxide, methyl halide, etc., are substituted again in a suitable reaction system or under the catalysis of a base, and finally 2-chloro-3-methoxylpyrazine is obtained.
Second, starting from other nitrogen-containing heterocyclic compounds. If a pyridine derivative containing a specific substituent is taken as an example, the pyridine ring is first modified through multi-step reactions, such as oxidation, reduction and other steps, the pyridine ring is converted into the prototype of the pyridine ring. Then according to the above-mentioned similar chlorination and methoxylation reactions, chlorine atoms and methoxy groups are gradually introduced, and the reaction conditions can be finely adjusted to achieve the purpose of synthesizing 2-chloro-3-methoxypyrazine.
Third, the reaction path catalyzed by transition metals. Suitable transition metal catalysts, such as palladium and copper complexes, can be selected.
