Adding a certain compound to certain chemical reactions, such as: 6164-79-0, name is Methyl 2-pyrazinecarboxylate, belongs to Pyrazines compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 6164-79-0, Product Details of 6164-79-0
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.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, Methyl 2-pyrazinecarboxylate, other downstream synthetic routes, hurry up and to see.
