Procedure

Ethyl 4-(2-{(3,5-bis-trifluoromethyl-benzyl)-[2-((S)-1-hydroxymethyl-propylamino)-5-trifluoromethyl-benzyl]-amino}-pyrimidin-5-yloxy)-butyrate (40 mg) is dissolved in a mixed solvent of methanol (0.3 ml) and tetrahydrofuran (1 ml) and thereto is added a 1M-aqueous sodium hydroxide solution (0.5 ml), and the mixture is stirred at room temperature for 30 minutes. To reaction mixture are added a 10% aqueous citric acid solution and a saturated brine, and the mixture is extracted with ethyl acetate. The organic layer is washed with a saturated brine, dried over magnesium sulfate, and concentrated under reduced pressure to give 4-(2-{(3,5-bis-trifluoromethyl-benzyl)-[2-((S)-1-hydroxymethyl-propylamino)-5-trifluoromethyl-benzyl]-amino}-pyrimidin-5-yloxy)-butyric acid (41 mg). MS (m/z): 669 [M+H]+
