Adding a certain compound to certain chemical reactions, such as: 4858-85-9, name is 2,3-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 4858-85-9, Recommanded Product: 2,3-Dichloropyrazine
Hydrazine hydrate (20 mL, 43.6 mmol) was slowly added dropwise to a solution of 2,3-dichloropyrazine (3.2 g, 21.8 mmol) in ethanol (600 mL).The temperature was raised to reflux for 1.5 hours, and the mixture was dried under reduced pressure.The solid is added to the water and filtered.The solid was recrystallized twice in ethanol to give a yellow solid(2.68 g, yield 85%).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 2,3-Dichloropyrazine, and friends who are interested can also refer to it.
