Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 87486-34-8, name is 3,5-Dibromo-1-methylpyrazin-2(1H)-one, A new synthetic method of this compound is introduced below., Recommanded Product: 3,5-Dibromo-1-methylpyrazin-2(1H)-one
A mixture of tert-butyl 6-amino-3,4-dihydroisoquinoline-2(lH)-carboxylate (3 g, 12mmol), 3,5-dibromo-l-methylpyrazin-2(lH)-one (2.68 g, lOmmol), and triethylamine (1.5 g, 15mmol) in IPA (50 mL) was heated at 70¡ãC for 15 h. The mixture was cooled to room temperature. The resulting yellow solids were collected by filtration and dried in vacuum to afford 120a as a yellow solid (2.83 g, 65 ).MS: [M+H]+ 435.
The synthetic route of 87486-34-8 has been constantly updated, and we look forward to future research findings.
