A highly efficient, green and simple solvent-free method for the synthesis of 1-amidoalkyl-2-naphtholsviaone-pot multi-components condensation of 2-naphthol, aromatic aldehydes and amides in the presence of catalytic amount of silica-supported molybdatophosphoric acid (H3PMo12O40.xH2O/SiO2, 3.17 mol%) is described. The reactions proceed rapidly and the title compounds are produced in high to excellent yields.
