2-{(3,5-Bis-trifluoromethyl-benzyl)-[2-(cyclohexylmethyl-ethyl-amino)-5-trifluoromethyl-benzyl]-amino}-pyrimidin-5-ol (250 mg) and 3-bromo-1-propanol (43 μl) are dissolved in N,N-dimethylformamide (1 ml) and thereto is added potassium carbonate (65 mg) and the mixture is stirred at room temperature overnight. Thereto are added ethyl acetate and a saturated brine, 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 (hexane:ethyl acetate=9:1→3:1) to give 3-(2-{(3,5-bis-trifluoromethyl-benzyl)-[2-(cyclohexylmethyl-ethyl-amino)-5-trifluoromethyl-benzyl]-amino}-pyrimidin-5-yloxy)-propan-1-ol (150 g).
