The procedure involves a novel three-component reaction of 1-naphthol or 2-naphthol; acetophenone derivatives and triethyl orthobenzoate in the presence of silica supported ionic liquid [pmim]HSO 4 SiO2 [silica supported
1-methyl-3-(triethoxysilylpropyl)imidazolium hydrogensulfate] as an effi cient catalyst.},
