Multicomponent Synthesis and Invitro study of Amino Pyrazole Employed by Et3N as a Catalyst

In the present study and followed by conventional method, an efficient and design synthesis a novel series of 5-Amino-1,3-diphenyl-1H-pyrazole-4-carbonitrile derivatives. These derivatives can be obtained by Phenyl hydrazine, aromatic aldehydes, and malononitrile in presence of base catalyst Et3N in DCM as a solvent at reflux. All the newly obtained derivatives were evaluated by the advanced spectroscopic analysis such as 1HNMR, 13CNMR and LCMS and structural determination of titled analogous were calculated by elemental analysis. In addition to the newly synthesised compounds were examined by their anti-microbial activity. This environmentally benign and practical method offers many advantages, such as mild reaction conditions, high yields, use of available catalyst, mild reaction conditions and easy workup.
