Adding a certain compound to certain chemical reactions, such as: 33332-28-4, name is 2-Amino-6-chloropyrazine, 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 33332-28-4, Recommanded Product: 2-Amino-6-chloropyrazine
(b) N-(6-Chloro-pyrazin-2-yl)-4-hydroxy-2-methyl-2H-1,2-benzothiazine-3-carboxamide-1,1-dioxide This compound was prepared from 4-hydroxy-2-methyl-N-methyl-2H-1,2-benzothiazine-3-carboxamide-1,1-dioxide, 2-amino-6-chloro-pyrazine and p-toluenesulfonic acid analogous to Example 14. Yield: 68percent of theory. Melting point: 278¡ã-279¡ã C. (decomposition). C14 H11 ClN4 O4 S (366.79): Calc.: C–45.84percent; H–3.03percent; Cl–9.67percent; N–15.28percent; S–8.74percent. Found: C–45.61percent; H–3.14percent; Cl–9.71percent; N–15.02percent; S–8.58percent.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 2-Amino-6-chloropyrazine, and friends who are interested can also refer to it.
