Synthetic Route of 87486-34-8, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 87486-34-8, name is 3,5-Dibromo-1-methylpyrazin-2(1H)-one belongs to pyrazines compound, it is a common compound, a new synthetic route is introduced below.
General procedure: To a solution of 2a-j (10 mmol, 1.0 eq) , 3,5-dibromo-1-methylpyrazin-2(1H)-one (2.95 g, 11 mmol, 1.1 eq) and DIEA (3.3 mL,20 mmol, 2.0 eq) in MeCN (20mL) was stirred at 80 °C for 5 hours. After cooling to room temperature, thesolvent was removed in vacuo, and the residue was purified using silica gelchromatography to give the title compounds, yield 72-85percent.
The synthetic route of 3,5-Dibromo-1-methylpyrazin-2(1H)-one has been constantly updated, and we look forward to future research findings.
