Abstract

The main objective of this work is to synthesise some new imidazolones and at the same time to reduce reflux time and to increase percent yield of the product. Imidazolones are reported to show several pharmacological activities .The work presented here involves preparation of oxazolones from benzoylglycine and substituted aldehydes in presence of anhydrous sodium acetate and acetic anhydride .These oxazolones were further reacted with aniline in presence of Zeolite as a catalyst to afford the formation of -5-imidazolones.The characterisation of newly synthesized compounds was made by chemical properties, elemental analysis and FT-IR,1H-NMR By employing zeolite as a catalyst , we could reduce reflux time substantially and increase percent yield of the product.
