Uses

Used in Pharmaceutical Industry:
2-Chloro-6-methylpyrazine is used as a synthetic intermediate for the development of various pharmaceutical compounds. Its unique chemical structure allows it to be a key component in the synthesis of palm site inhibitors of HCV NS5B polymerase, which are essential in the treatment of Hepatitis C Virus (HCV) infections. These inhibitors help to block the replication of the virus, thereby reducing its impact on the infected individual.
Additionally, 2-Chloro-6-methylpyrazine is also used as a synthetic intermediate for the development of potent dipeptidyl peptidase IV (DPP-IV) inhibitors. DPP-IV inhibitors play a crucial role in the management of type 2 diabetes by regulating the levels of glucose in the body. They work by increasing the levels of insulin and decreasing the levels of glucagon, thus helping to maintain a balanced blood sugar level.

Production method of 2-methyl-3(5 or 6)-methylthio pyrazine

The invention discloses a production method of 2-methyl-3(5 or 6)-methylthio pyrazine. The method comprises the following steps: adding solvents dichloroethane and triethylamine into a reaction kettle, sealing the reaction kettle, introducing chlorine to control the pressure in the kettle at 0.02-0.03 MPa, pumping a methylpyrazine solution into the reaction kettle by using a metering pump, controlling the temperature at 45-60 DEG C, reacting, and transferring reaction liquid(containing the chlorine)in the kettle into a dichloroethane turnover tank through filter pressing for recycling after the reaction is finished; dissolving the residual 2-methyl-3(5 or 6)-chloropyrazine hydrochloride solid in the reaction kettle with water, adjusting the neutrality, and layering to obtain a 2-methyl-3(5or 6)-chloropyrazine crude product; and dropwise adding thechloropyrazine crude product is into sodium methyl mercaptide, performing reflux reaction , and after reaction liquid is extracted, adding an aid into an organic phase to generate a hydrochloride for separating the non-pyrazine product from the product to greatly improve the aroma quality of the obtained product. The product grade is improved, and the whole production process is safe and environmentally friendly.

Reactions of Halogenomethanes in the Vapor Phase. Part 4. The Reactions of Imidazoles with Chloroform at 550 deg C, and a Comparison with their Liquid-phase Reactions with Trichloroacetate Ion or Hexachloroacetone and Base

1-Unsubstituted imidazoles and chloroform at 550 deg C in a flow system give mainly 5-chloropyrimidines, together with 4-chloropyrimidines and chloropyrazines.The effects of methyl substituents on the ratio of products is considered.The liquid-phase reactions of 2-methyl- and 2,4,5-trimethyl-imidazole under conditions in which dichlorocarbene is said to be formed in basic or neutral conditions were studied, and compared with the gas-phase reactions with chloroform.
