To a melted liquid of 38.8 g of hexanoic acid, 4-tetradecylphenyl ester at 80°-95° C. was added 26.67 g of aluminum chloride in small portions over a period of 2 hours. This mixture was heated for an additional hour, then allowed to cool, diluted with ether and poured onto ice containing 10 ml of concentrated hydrochloric acid. The organic layer was washed with water, dried and the solvent evaporated. The residue was chromatographed on silica gel, eluting with hexane:ethyl acetate (50:1), giving 33 g of the desired compound, mp 41°-42° C.
