Reaction Steps

In 155 ml of ethanol is dissolved 30.9 g of methyl 3-[5-(2-hydroxy-4-isobutoxybenzoyl)-2-isobutoxyphenyl]propanoate, to which is added 44 ml of 5 mol/L solution of sodium hydroxide. The mixture is stirred at ambient temperature for one hour. Water, followed by chloroform, is 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 the solvent is distilled off under reduced pressure. Thus, 29.5 g of 3-[5-(2-hydroxy-4-isobutoxybenzoyl)-2-isobutoxyphenyl]-propanoic acid is obtained as a yellow-white colored solid product.
