Reaction Steps

Ethyl 4-{2-[(3,5-bis-trifluoromethyl-benzyl)-(2-hydroxy-5-trifluoromethyl-benzyl)-amino]-pyrimidin-5-yloxy}-butyrate (200 mg) is dissolved in N,N-dimethylformamide (3 ml), and thereto are added 2-chloropyrimidine (45 mg) and potassium carbonate (55 mg), and the mixture is stirred at 85° C. overnight. The reaction solution is cooled to room temperature, and thereto 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=41:9→13:7) to give ethyl 4-(2-{(3,5-bis-trifluoromethyl-benzyl)-[2-(pyrimidin-2-yloxy)-5-trifluoromethyl-benzyl]-amino}-pyrimidin-5-yloxy)-butyrate (120 mg). MS (m/z): 704 [M+H]+
