Synthetic Route of 13134-31-1,Some common heterocyclic compound, 13134-31-1, name is 2,3-Diaminopyrazine, molecular formula is C4H6N4, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
(a) 2-(2,4-Dimethoxy-5-chlorosulfonyl-phenyl)-imidazo-[4,5-b]-pyrazine was prepared analogous to Example 2 from 2,3-diaminopyrazine and 2,4-dimethoxy-5-chlorosulfonyl-benzoylchloride. M.p. 294-296 C.
The synthetic route of 13134-31-1 has been constantly updated, and we look forward to future research findings.
