To a solution of 14.7 g of 6-(1,4-Dimethoxy-3-methylnaphthalen-2-yl)-6-(4-methoxyphenyl)hexanoic acid in 300 ml of acetonitrile at 0C was added an aqueous 147 ml solution of 57.2 g of ceric ammonium nitrate portionwisely over 5 min. After stirring for 16 hours at room temperature, the solution was extracted with ethyl acetate. The organic layer was washed, dried, evaporated, and the residue was purified with column chromatography over silica gel using ethyl acetate as an eluent. Recrystallization from isopropyl ether/ethyl acetate gave 10.8 g of the title compound.
