6164-79-0, Name is Methyl 2-pyrazinecarboxylate, 6164-79-0, belongs to Pyrazines compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows.

Methyl 3-oxo-3-(pyrazin-2-yl)propanoate: To a stirred solution of sodium methoxide (25% in MeOH, 27.54 mL, 72.4 mmol, 1 eq) in 90 mL of toluene at 110 C. in a 3-neck flask attached with a mechanical stirrer, condenser and dropping funnel was added a solution of methylpyrazine-2-carboxylate (10 g, 72.4 mmol, 1 eq) in 115 mL of methyl acetate, dropwise, over a period of ?35-40 min. A yellow precipitate was formed. Stirring was continued at 110 C. for 3 hrs. The reaction was cooled and the yellow precipitate was filtered and washed with a small quantity of toluene. This solid was taken into 200 mL of saturated ammonium chloride and 400 mL of EtOAc. The aqueous layer was extracted twice with EtOAc. The combined organic layers were dried over magnesium sulfate, filtered and evaporated to give 6.52 g (50%) of methyl 3-oxo-3-(pyrazin-2-yl)propanoate as a yellow solid.

Statistics shows that Methyl 2-pyrazinecarboxylate is playing an increasingly important role. we look forward to future research findings about 6164-79-0.
