The first synthetic route for 6-chloro-2-pyrazinecarbonitrile involves the reaction of 2-cyanopyrimidine with chloroform.
In this reaction, 2-cyanopyrimidine is first treated with chloroform in the presence of a base, such as sodium hydroxide.
The resulting product is then reacted with a chlorinating agent, such as chlorine or N-chlorosuccinimide, to introduce the chlorine atom.
This route is relatively simple and can be performed using easily available reagents.

Another synthetic route for 6-chloro-2-pyrazinecarbonitrile involves the reaction of 2-aminopyrimidine with chloroacetamide in the presence of a strong acid catalyst, such as sulfuric acid.
In this reaction, the amino group of 2-aminopyrimidine is first converted to a trifluoroacetamide, which is then treated with chloroacetamide and a strong acid catalyst.
The resulting product is then hydrolyzed to produce 6-chloro-2-pyrazinecarbonitrile.
This route is also relatively simple and can be performed using easily available reagents.

A third synthetic route for 6-chloro-2-pyrazinecarbonitrile involves the reaction of 2-pyrimidinamine with chloroformaldehyde in the presence of a base, such as sodium hydroxide.
In this reaction, 2-pyrimidinamine is treated with chloroformaldehyde and the resulting product is then hydrolyzed to produce 6-chloro-2-pyrazinecarbonitrile.
This route is commonly used in industry and can be performed using easily available reagents.

There are also several other synthetic routes for 6-chloro-2-pyrazinecarbonitrile, including those that involve the use of reagents such as potassium permanganate, thionyl chloride, and others.
These routes may be more complex or require the use of more specialized reagents, but they can still be effective for synthesizing this compound.

Overall, the synthetic routes for 6-chloro-2-pyrazinecarbonitrile are varied and can be tailored to specific synthetic requirements and industrial applications.
Each route has its own advantages and disadvantages, and the choice of route will depend on the specific needs of the synthesis.
Regardless of the route chosen, 6-chloro-2-pyrazinecarbonitrile is an important building block in the synthesis of a wide range of chemicals and pharmaceuticals, and its synthesis continues to be an active area of research and development in the chemical industry.
