Abstract: Ethyl 4-[2-(2-chlorophenyl)-4-oxo-3-hydroquinazolin-3yl]benzoate 1 which reacts with hydrazine hydrate in presence of methanol resulted into N-amino{4-[2-(2-chlorophenyl)-4-oxo(3-hydroquinazolin-3-yl)phenyl}carboxamide 2. Compound 2 on treatment with aryl isothiocyanates in presence of acetone is converted into aryl-N-{[({4-[2- (2-chlorophenyl)-4-oxo(3-hydroquinazolin-3-yl)]phenyl}carbonylamino)amino]thioxo methyl}amides 3. Compound 3, in presence of sulphuric acid has yielded aryl-N-(5-{4-[2-(2-chlorophenyl)-4-oxo(3-hydroquinazolin-3-yl)]phenyl}(1,3,4,thiadiazol-2-yl))amides 4a-l. Newly synthesized compounds 4a-l have been screened for their antibacterial and antifungal activities on Eschericia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Staphylococcus pyogenes, C. albicans, A. niger and A. clavatus.
