• Amidoalkyl naphthol
• Nano-sulfated zirconia
• Solvent free
• Multicomponent

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