One pot synthesis of amidoalkyl naphthol by condensation of aromatic aldehydes, 2-naphthol and amide/urea using silicotungstic acid as a catalyst is reported. The reaction was carried out under solvent-free reaction conditions. The method gave good yields of amidoalkyl naphthols in short reaction time compared with previous methods. The catalyst is recycled for five consecutive times without loss of activity.
