実験手順
A solution of 0.945 g (0.0016 mole) of [4-acetyl-3-[5-(4-acetyl-6-chloro-3-hydroxy-2-propylphenoxy)pentyloxy]-2-propylphenoxy]acetic acid ethyl ester in 50 ml of methanol and 8.2 ml (0.0082 mole) of 1.0N sodium hydroxide was stirred at reflux for 2 hours. Most of the solvent was removed in vacuo and the pH of the residue was adjusted to 2.0. The product was extracted with methylene chloride and the dried (magnesium sulfate) extract was concentrated in vacuo. The residue was crystallized from ether-hexane to give 0.710 g (79% yield) of [4-acetyl-3-[5-(4-acetyl-6-chloro-3-hydroxy-2-propylphenoxy)pentyloxy]-2-propylphenoxy]acetic acid, melting point 77°-80°.
