In 88 ml of ethanol is dissolved 17.48 g of isobutyl 2,5-diisobutoxybenzoate. After adding 33 ml of 5 mol/L sodium hydroxide solution, the mixture is stirred at ambient temperature for 30 minutes. 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 washed with water and saturated aqueous solution of sodium chloride successively and dried over anhydrous magnesium sulfate, and then the solvent is distilled off under reduced pressure. Thus, 12.16 g of 2,5-diisobutoxybenzoic acid is obtained as a white solid product.
