51171-02-9, name is Methyl 3-Bromo-2-pyrazinecarboxylate, 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. Recommanded Product: Methyl 3-Bromo-2-pyrazinecarboxylate
A solution of 3-bromopyrazine-2-carboxylic acid methyl ester (0.10 g, 0.45 mmol), 2- tritylsulfanylethylamine (0.29 g, 0.90 mmol) and triethylamine (0.06 mL, 0.44 mmol) in acetonitrile (5 mL) was heated to reflux for 18 h under argon. The mixture was concentrated under reduced pressure and purified by column chromatography (3:1 Hex:EtOAc), yielding 0.058 g (28%) of the desired product.
The synthetic route of 51171-02-9 has been constantly updated, and we look forward to future research findings.
