Procedure

In 9 ml of ethanol is dissolved 1.74 g of ethyl 3-[5-(3,5-diisobutoxybenzoyl)-2-isobutoxyphenyl]-propanoate. After adding 2 ml of 5 mol/L solution of sodium hydroxide, the mixture thus obtained is stirred at ambient temperature for one hour. Chloroform and water are added to the reaction mixture, pH is adjusted to 2 with 6 mol/L hydrochloric acid, and the organic layer is separated. The organic layer is successively washed with water and saturated aqueous solution of sodium chloride and dried over anhydrous magnesium sulfate, and the solvent is distilled off under reduced pressure. Thus, 1.53 g of 3-[5-(3,5-diisobutoxybenzoyl)-2-isobutoxyphenyl]propanoic acid is obtained as a white solid product.
