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

A solution of 3-amino-1-phenyl-2-pyrazolin-5-one 1 (0.35 g, 2 mmol), dimedone 2 (0.28 g, 2 mmol), aldehyde 3 (0.28 mg, 2 mmol) and Cell-LA-TEA+\/Fe3O4 nanocatalyst (0.03 g, 0.09 mol%) in H2O\/EtOH (3:2) was subjected to ultrasonic irradiation (ultrasonic bath, room temperature). The progress of the reaction was controlled by TLC (hexane\/ethyl acetate, 2:3). After reaction completion, the nanocatalyst was separated magnetically from the reaction mixture and used for subsequent cycles after washing with ethanol. By cooling the reaction solution, the solid product was collected, separated and recrystallized from methanol to get the pure product.<\/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
