Procedure

Ethyl 4-(2-{(3,5-bis-trifluoromethyl-benzyl)-[2-(1,3-diethylureido)-5-trifluoromethyl-benzyl]-amino}-pyrimidin-5-yloxy)-butyrate (165 mg) is dissolved in ethanol (3 ml) and thereto is added 2N-aqueous sodium hydroxide solution (342 μl) and the mixture is stirred at room temperature overnight. To the reaction solution are added ethyl acetate and a 1N-hydrochloric acid, 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→17:3) to give 4-(2-{(3,5-bis-trifluoromethyl-benzyl)-[2-(1,3-diethylureido)-5-trifluoromethyl-benzyl]-amino}-pyrimidin-5-yloxy)-butyric acid (68 mg). MS (m/z): 696 [M+H]+
