An efficient and direct procedure has been developed for the preparation of amidoalkyl naphthols by a one-pot condensation of aryl aldehydes,2-naphthol and urea or amides,in the presence of HClO4-SiO2 as a heterogeneous catalyst.The reactions were carried out under reflux and solvent-free conditions.The present methodology offers several advantages such as excellent yields,simple procedure,easy work-up and ecofriendly reaction condition.The catalystis easily prepared,stable,reusable and efficient under the reaction conditions.
