Electric Literature of 3149-28-8, A common heterocyclic compound, 3149-28-8, name is 2-Methoxypyrazine, molecular formula is C5H6N2O, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: Perfluorobutanesulfonyl azides 1a (715 mg, 2.2 mmol) and pyrazine 2a (2.0 mmol) was mixed without solvent at room temperature, this reaction mixture stirred for 8 h at 120 C, TLC analysis showed the reaction was completed. The product 3aa was obtained by flash column chromatography (using petroleum ether/ethyl acetate=2:1 as eluant) as a yellow solid in 34% yield (234 mg).
The synthetic route of 3149-28-8 has been constantly updated, and we look forward to future research findings.
