Application of 14508-49-7, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 14508-49-7 as follows.
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.
According to the analysis of related databases, 14508-49-7, the application of this compound in the production field has become more and more popular.
