A solution of 2.30 g of 4-[4-acetyl-3-[2-[2-[2-[2-(4-acetyl-3-hydroxy-2-propylphenoxy)ethoxy]ethoxy]ethoxy]ethoxy]-2-propylphenoxy]butanoic acid ethyl ester in 17 ml of 1.0N sodium hydroxide and 50 ml of methanol was stirred at reflux for 7 hours. The methanol was removed in vacuo and the residue was acidified. The product was extracted with ether and the dried (magnesium sulfate) extract was concentrated in vacuo to an oil (2.40 g). Chromatography on 150 g of silica gel and elution with a solvent mixture of 5% acetic acid: 70% toluene: 25% ethyl acetate gave 1.72 g (78% yield) of 4-[4-acetyl-3-[2-[2-[2-[2-(4-acetyl-3-hydroxy-2-propylphenoxy)ethoxy]ethoxy]ethoxy]ethoxy]-2-propylphenoxy]butanoic acid as a viscous oil.
