ABSTRACT
A new series of ethyl 6-methyl-4-[substituted]phenyl-2-[substituted]-phenacyl-thio-1, 4- dihydropyrimidine-5-carboxylate [2a-x] was prepared by reaction of ethyl 1, 2, 3, 4-tetrahydro-6-methyl-4-[substituted]phenyl-2-thioxopyrimidine-5-carboxy-late J [a-d] with phenacyl bromides. Compounds 1[a-d] were synthesized using the principle of Bignelli condensation by one pot reaction of the appropriate araldehyde. ethyl acetoacetate and thiourea in acidic medium. Confirmation of the chemical structure of the synthesized compounds [2a-x] was substintiated by different spectral data IR. [1]H-NMR. MS in addition to their microanalyses. The newly synthesized compounds were evaluated for their antimicrobial activities. The antibacterial and antifungal testing identified compounds 2b, 2e, 2k, 21, 2m, 2n, 20, 2p, 2q, 2, and 2x as the most effective agents in comparison to Chloramphenicol and Clotrimazole as reference antibacterial and antifungal drugs respectively
