실험 절차

Ethyl 4-{2-[(3,5-bis-trifluoromethyl-benzyl)-(2-hydroxy-5-trifluoromethyl-benzyl)-amino]-pyrimidin-5-yloxy}-butyrate (300 mg) is dissolved in N,N-dimethylformamide (5 ml) and thereto are added sodium hydride (60%) (29 mg) and 4,6-dichloro-pyrimidine (107 mg) under ice-cooling, and the mixture is stirred for 30 minutes, and the reaction solution is cooled to room temperature, and thereto is added 4,6-dichloro-pyrimidine (107 mg), and the mixture is stirred for 30 minutes. To the reaction solution are added water 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 (hexane:ethyl acetate=49:1→17:1) to give ethyl 4-(2-{(3,5-bis-trifluoromethyl-benzyl)-[2-(6-chloro-pyrimidin-4-yloxy)-5-trifluoromethyl-benzyl]-amino}-pyrimidin-5-yloxy)-butyrate (244 mg). MS (m/z): 738/740 [M+H]+
