Abstract: Amido/imido alcohol/2-phenyl-3-hydroxyethylquinazolin-4 (3<i>H</i>) -one <b>1</b> on treatment with benzoic acid in the presence of conc. H<sub>2</sub>SO<sub>4</sub> yields <i>m-</i>(aralkylamido/imidoalkyl/2-phenyl-3-ethyl-3<i>H</i>-4-oxoquinazolinyl) benzoic acids <b>2</b>. The acid chloride of <b>2</b> on reaction with hydrazine hydrate affords <i>m-</i>(aralkylamido/imidoalkyl/2-phenyl-3-ethyl-3<i>H</i>-4-oxo-quinazolinyl) benzoic acid hydrazides <b>4</b> which on condensation with an aromatic aldehyde in acetic acid gives <i>m</i>-(aralkylamido/imidoalkyl/2-phenyl-3-ethyl-3<i>H</i>-4-oxo-quinazolinyl) benzoic acid hydrazones <b>5</b>. Compounds <b>5</b> undergo cyclization with phenoxy acetic acid in the presence of thionyl chloride in dry benzene to furnish 1-[<i>m</i>-(aralkylamido/imidoalkyl/2-phenyl-3-ethyl-3<i>H</i>-4-oxo-quinazolinyl-benzamido)]-3-phenoxy-4-phenyl-2-azetidinones <b>6</b>. The antiviral and antifungal activities of <b>6</b> have been reported.
