Reference 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-trifluoromethylpyrazole (5.0 g, 36 mmol), triethylamine (7.0 mL, 50 mmol) in dichloromethane (40 mL) was added dimethylsulfamoyl chloride (5.5 mL, 51 mmol), and the reaction mixture was heated at reflux for 2 days. The resulting mixture was cooled to ambient temperature and filtered through a pad of silica gel using dichloromethane as eluent. The filtrate was then concentrated under reduced pressure to give an amber residue. The resulting residue was dissolved in diethyl ether. The ether solution was washed with water, dried (MgSC^), and concentrated under reduced pressure to give 8.71 g of the title compound. 1HNMR (CDCl3) delta 3.01 (s, 6H), 6.65 (s, IH)5 8.03 (s, IH).<\/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
