ABSTRACT:
A novel compound is disclosed having the structure ##STR1## in which R is H or lower alkyl, R* is intermediate alkyl, and X is halogen or pseudohalogen. Also disclosed is a method for preparing the compound, the method including the steps of reacting (intermediate alkyl)benzene (I) with succinic anhydride to form (intermediate alkyl)-benzoylpropionic acid (II), successively reducing and dehydrating (II) to form 7-(intermediate alkyl)-1-tetralone (III), alkylating (III) to form 2-hydroxy(lower alkylidene)-7-(intermediate alkyl)-1-tetralone (IV), acrylating (IV) to form 2-acyloxy(lower alkylidene)-7-(intermediate alkyl)-1-tetralone (V), reacting (V) in the presence of an cycloalkene to form 7(intermediate alkyl)-2-(lower alkyl)-1-naphthol (VI), reacting (VI) with a 2,6-dihaloquinone-4-haloimide to form the compound (I), and isolating it.
