Reaction Steps
In 7 ml of ethanol is dissolved 1.26 g of ethyl 3-(5-{(2,4-diisobutoxyphenyl)[(methylsulfonyl)-amino]methyl}-2-isobutoxyphenyl)propanoate, to which is added 1.3 ml of 5 mol/L solution of sodium hydroxide. The mixture is stirred at ambient temperature for one hour. Water and chloroform 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 the solvent is distilled off under reduced pressure. The residue thus obtained is purified by silica gel column chromatography (eluent; hexane:ethyl acetate=1:1) to obtain 0.92 g of 3-(5-{(2,4-diisobutoxyphenyl)[(methylsulfonyl)amino]methyl}-2-isobutoxyphenyl)propanoic acid as a light yellow oily product.
