The chemical industry reduces the impact on the environment during synthesis 51516-67-7, name is 5-Amino-1-(4-chlorophenyl)-1H-pyrazole-4-carbonitrile, I believe this compound will play a more active role in future production and life. 51516-67-7
General procedure: A mixture of theintermediate compounds 2 (1 mmol) and 3 (1 mmol) in ethanol(10 mL) was stirred at reflux for 2 h. After cooling to roomtemperature, the precipitated solid was filtered, and thenrecrystallized from ethanol to give the title compounds 5a-5p.
