Application of 20154-03-4<\/a>,Some common heterocyclic compound, 20154-03-4, name is 3-(Trifluoromethyl)-1H-pyrazole, molecular formula is C4H3F3N2, 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

To a solution of 3-trifluoromethyl-1H-pyrazole (500 mg, 3.67 mmol) in glacial acetic acid (5 ml) was added a 10percent solution of sodium hypochlorite in water (2188 mul, 3.67 mmol). The reaction mixture was stirred at RT overnight and then neutralized with sat. sodium carbonate, and extracted with DCM. The organic layers were combined washed with brine, dried (MgSO4), filtered and concentrated in vacuo to give the desired product (480 mg, 77percent) as a white solid which did not require further purification. MS (ISP) 169.0 (M-H)-.<\/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 3-(Trifluoromethyl)-1H-pyrazole, its application will become more common.<\/p>\n
