Abstract
In this thesis the synthesis of 4-(4-(dimethylamino)phenyl)-3-methyl-4,5-dihydro-1H-pyrazolo[3,4-d]pyrimidine-6-thiol 1, 4-(6-hydrazinyl-3-methyl-4,5-dihydro-1H-pyrazolo[3,4-d]pyrimidin-4-yl)-N,N-dimethylaniline 10 and 6-amino-4-(4-(dimethylamino)phenyl)-3-methyl-1,4-dihydropyrano[2,3-c]pyrazole-5-carbonitrile 24 were reported. Subsequently, the behavior of these compounds towards different chemical reagents was studied to produce new heterocyclic compounds having expected antimicrobial activities.
