Reference of 57999-06-1<\/a>,Some common heterocyclic compound, 57999-06-1, name is 4-Phenyl-1H-pyrazol-5-amine, molecular formula is C9H9N3, 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.<\/p>\n

General procedure: A suspension of 3(5)-amino-4-(thien-2-yl)pyrazole (1h) or 3(5)-amino-4-phenylpyrazole (1i) 11,13 (10 mmoles) and ethyl 2-(pyrazol-10-yl)-2-formylacetate (A) or ethyl 2-(imidazol-10-yl)-2-formylacetate (B) (10 mmoles) in dyglime (20 mL) was refluxed under magnetic stirring until the starting material disappeared. The precipitate was collected by filtration from the reaction mixture and recrystallized by suitable solvent, obtaining compounds 5a, 5b, 6a and 6b respectively.<\/p>\n

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 4-Phenyl-1H-pyrazol-5-amine, its application will become more common.<\/p>\n","protected":false},"excerpt":{"rendered":"
