Procedure
Ethyl 4-(2-{(3,5-bis-trifluoromethyl-benzyl)-[2-(4-methyl-pyridin-2-yl)-5-trifluoromethyl-benzyl]-amino}-pyrimidin-5-yloxy)-butyrate (85 mg) is dissolved in ethanol (4 ml), and thereto is added 1N-aqueous sodium hydroxide solution (1 ml) and the mixture is stirred at room temperature for 45 minutes. To the reaction solution are added a 1N-hydrochloric acid and ethyl acetate, and the mixture is separated, and the organic layer is washed with a saturated brine, dried over magnesium sulfate, and concentrated under reduced pressure. The resulting residue is purified by silica gel column chromatography (chloroform:methanol=1:0→23:2) to give 4-(2-{(3,5-bis-trifluoromethyl-benzyl)-[2-(4-methylpyridin-2-yl)-5-trifluoromethyl-benzyl]-amino}-pyrimidin-5-yloxy)-butyric acid (68 mg). The resulting carboxylic acid is dissolved in ethanol (1 ml), and thereto is added 1N-aqueous sodium hydroxide solution (101 μl), and the reaction solution is concentrated under reduced pressure to give 4-(2-{(3,5-bis-trifluoromethyl-benzyl)-[2-(4-methyl-pyridin-2-yl)-5-trifluoromethyl-benzyl]-amino}-pyrimidin-5-yloxy)-butyric acid sodium salt (69 mg).
