Procedure
To a solution of 13.5 g of phosphoric acid, 1-[[(4-methoxyphenyl)diphenylmethoxy]-methyl]-2-(pentyloxy)ethyl methyl pentyl ester in 68 ml of chloroform and 136 ml of methyl alcohol heated to boiling is slowly added 6.8 g of Amberlyst®-15 resin. The heat is removed and the mixture stirred at ambient temperature for 2 hours. The volatiles are removed and the residue dissolved in chloroform then washed with dilute sodium bicarbonate, dried and evaporated to an oily residue which is purified on silica gel using 1:1 ethyl acetate:hexanes to give 6 g of the desired compound as a colorless oil.
