Electric Literature of 14531-55-6,Some common heterocyclic compound, 14531-55-6, name is 3,5-Dimethyl-4-nitro-1H-pyrazole, molecular formula is C5H7N3O2, 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.
General procedure: A solution of pyrazole (2.04g, 0.03mol) in freshly distilled THF (20mL) was added to a stirred suspension of sodium hydride (60%, 2.04g, 0.03mol) in 20mL THF at room temperature. After 1h, Cyanuric chloride (1.85g, 0.01mol) in THF (15mL) was added to the above solution and white precipitate was formed. After being stirred and heating at 70C for 5h, the solution was filtered off, the filtrate evaporated on a steam bath, and then washed with hot-water. 2,4,6-tri(1H-pyrazol-1-yl)methyl)-1,3,5-triazine.
The synthetic route of 14531-55-6 has been constantly updated, and we look forward to future research findings.
