AN EFFICIENT MICROWAVE ASSISTED MULTICOMPONENT SYNTHESIS OF SOME 7-AMINO-3- (SUBSTITUTED PHENYL)-5-(SUBSTITUTED PHENYL)-(1,2,4)TRIAZOLO(4,3A)PYRIMIDINE-6- CARBONITRILE DERIVATIVES Research Article

A series of 7-amino-3-(substituted phenyl)-5-(substituted phenyl)-[1,2,4]triazolo [4,3a] pyrimidine-6-carbonitrile derivatives were synthesized from 4-amino-2-hydroxy (OR mercapto)-6-(substituted phenyl)-pyrimidine-5-carbonitrile, hydrazine hydrate and aromatic aldehydes. The derivatives were obtained in good yields by the microwave-assisted one-pot protocol in very short reaction time. The synthesized compounds were studied for QSAR by subjecting to a prediction of biological activities applying computer programme PASS. It is found that 7-Amino-3-(4-chlorophenyl)-5-(2,4-dichloro-phenyl)-[1,2,4]triazolo[4,3-a]pyrimidine-6-carbonitrile is a promising anticonvulsant agent; which can be synthesized by an efficient, promising, and green synthetic method with high yield.
