Adding a certain compound to certain chemical reactions, such as: 4774-14-5, name is 2,6-Dichloropyrazine, belongs to Pyrazines compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 4774-14-5, name: 2,6-Dichloropyrazine
General procedure: To a solution of absolute ethanol (5 mL) and dichlorodiazine (3.36 mmol) in a 50mL round-bottom flaskwas added triethylamine (5.03 mmol), followed by the amine (5.03 mmol). The mixture was stirred either under reflux of ethanol (for dichloropyridazine and for dichloropyrazine) or at room temperature (for dichloropyrimidines). The reaction was monitored by GC. Once the starting dichlorodiazinewas completely consumed, the mixture was poured into a saturated NH4Cl solution (20 mL), then extracted with CH2Cl2 (320 mL). The combined organic layers were dried over Na2SO4, filtered, and evaporated under vacuum. The crude solid was triturated in petroleum ether, filtered through a Buchner to afford the pure product.
