Synthetic Route of 120068-79-3,Some common heterocyclic compound, 120068-79-3, name is 5-Amino-1-(2,6-dichloro-4-(trifluoromethyl)phenyl)-1H-pyrazole-3-carbonitrile, molecular formula is C11H5Cl2F3N4, 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.
General procedure: A mixture of compound A (5 mmol) and corresponding benzaldehyde (5 mmol) in 10 mL ethanol was refluxed for 24 hours in a reaction flask wrapped up by silver paper. Upon the reactions completed (monitored by TLC), tawny solids were obtained through suction filtration. The precipitates were washed with ethanol (5 mLx3) and recrystallized from ethanol with 50-84% yields.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 5-Amino-1-(2,6-dichloro-4-(trifluoromethyl)phenyl)-1H-pyrazole-3-carbonitrile, its application will become more common.
