Electric Literature of 2820-37-3, A common heterocyclic compound, 2820-37-3, name is 3,4-Dimethyl-1H-pyrazole, molecular formula is C5H8N2, its 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.
EXAMPLE 63 N,N,alpha,3,4-Pentamethylpyrazole-1-acetamide and N,N,alpha,4,5-pentamethylpyrazole-1-acetamide Following the procedure of Example 36, Part B, but substituting 3,4-dimethylpyrazole for 4-bromo-3-isopropylpyrazole, there was prepared N,N,alpha,3,4-pentamethylpyrazole-1-acetamide having a boiling point at 77 C. at 0.03 mm Hg.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
