4149-06-8, name is 3-Amino-1-phenyl-1H-pyrazol-5(4H)-one, belongs to pyrazoles-derivatives compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Recommanded Product: 3-Amino-1-phenyl-1H-pyrazol-5(4H)-one<\/a><\/p>\n

General procedure: The mixture of alpha,beta-unsaturated ketone 1, or 4 (1.0 mmol), 3-amino-1-phenyl-1H-pyrazol-5(4H)-one 2 (1.0 mmol), p-TSAxH2O (0.3mmol), MeCN (4mL), H2O (4mL) was put in a reaction flask under 80 C about 1-3 h (monitored by TLC). After completion, the reaction mixture was cooled to room temperature and the products would be precipitated out at same time. Then, it was filtered, washed thoroughly with MeCN. The products were recrystallized from DMF.<\/p>\n

The synthetic route of 4149-06-8 has been constantly updated, and we look forward to future research findings.<\/p>\n
