Procedure

A solution of 10 g of phosphoric acid, 2-(hexadecyloxy)-1-[[(4-methoxyphenyl)-diphenylmethoxy]methyl]ethyl methyl pentyl ester in 100 ml of methyl alcohol and 50 ml of chloroform is brought to a boil, the heat removed and 5 g of Amberlite®-15 resin carefully added. The reaction is stirred at ambient temperature for 2 hours, filtered to remove the resin and the cake washed well with 2:1 methyl alcohol:chloroform. The solvent is removed to give 9.7 g of a thick syrup. The product is chromatographed using dry column silica gel with 1:1 ethyl acetate:hexanes. Product fractions are combined and the solvents evaporated to give 1.38 g of a less polar isomer oily product and 1.46 g of a more polar isomer oily product.
