The aim of the study synthesis of new heterocyclic derivatives (six and five ring) from acetanilide. Firstly the chalcones have been synthesized from the reaction acetanilide with aromatic aldehyde [ 2-nitrobenzaldyhade. 4- dimethylaminobenzaldehyde. 2-naphthaldehyde ] in dilute solution of ethanolic sodium hydroxide at room temperature. https://www.incredibleindiatourtravels.com/
