Related Products of 51516-70-2,Some common heterocyclic compound, 51516-70-2, name is 5-Amino-1-(4-fluorophenyl)-1H-pyrazole-4-carbonitrile, molecular formula is C10H7FN4, 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: The experimental procedure was similar to synthesis of analogs1(aei). 5-amino-1-aryl-1H-pyrazole-4-carbonitriles 4(aei)(0.001 mol) were reacted with 2.0 mL of 1,3-diaminopropane andcarbon disulfide (0.004 mol). The temperaturewas 85-95oC and thereaction time was 14-16 hours. The reaction mixture was pouredinto cold water, the precipitate was filtered out and washed withcold water. The reactions were accompanied by means of TLC anddichloromethane as eluent.
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-(4-fluorophenyl)-1H-pyrazole-4-carbonitrile, its application will become more common.
