Related Products of 14508-49-7,Some common heterocyclic compound, 14508-49-7, name is 2-Chloropyrazine, molecular formula is C4H3ClN2, 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: 2,6-dichloropyrazine (10.49 g, 70.38 mmol) was dissolved in 150 mL of ethanol. After stirring for 5 min, 80% hydrazine hydrate (7.05 g, 0.147 mol) was added. The reaction was heated to 80 C and refluxed for 10 h until the solution became clear. The resulting mixture was cooled to room temperature, and a yellow solid was precipitated. The suspension was filtered, and the filtrate was concentrated under reduced pressure to afford a yellow solid 9.1 g.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-Chloropyrazine, its application will become more common.
