Reference of 4149-06-8<\/a>, These common heterocyclic compound, 4149-06-8, name is 3-Amino-1-phenyl-1H-pyrazol-5(4H)-one, 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.<\/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

Statistics shows that 3-Amino-1-phenyl-1H-pyrazol-5(4H)-one is playing an increasingly important role. we look forward to future research findings about 4149-06-8.<\/p>\n
