A series of 2-amino-3-cyano-4-aiylbenzo[ ft ] chromenes were synthesized by the reaction of arylmethlene malononitrile with 1- naphthol in the presence of triethylbenzylammoniurn chloride (TEBA) in water. The structures of all products were characterized by elemental analysis, IR and !H NMR spectra. Compared to the previous methods, this new protocol has the advantages of high yields, inexpensive medium and environmental friendlyness.
