Adding a certain compound to certain chemical reactions, such as: 63286-28-2, name is 2-Chloro-3-hydrazinylpyrazine, 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 63286-28-2, COA of Formula: C4H5ClN4
Add intermediate b (5.0 g, 0.034 mol) to triethyl orthoacetate (50 mL),The reaction was performed at 80 C, and the reaction time was monitored by spotting. The reaction liquid is directly filtered by cold suction,The filter cake was washed with petroleum ether, and the filter cake was dried to obtain 4.9 g of a yellow powder.The yield was 84.0%.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 2-Chloro-3-hydrazinylpyrazine, and friends who are interested can also refer to it.
