Reaction Steps

Ethyl 4-(2-{(3,5-bis-trifluoromethyl-benzyl)-[2-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-5-trifluoromethyl-benzyl]-amino}-pyrimidin-5-yloxy)-butyrate (200 mg) is dissolved in 1,4-dioxane (4 ml) and thereto are added 2-bromo-4-methyl-pyridine (70 mg), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium dichloromethane complex (22 mg) and cesium carbonate (133 mg), and the mixture is stirred under nitrogen atmosphere at 80° C. for 5 days. The reaction solution is cooled to room temperature, and thereto are added ethyl acetate and water, 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 NH-silica gel column chromatography (hexane:ethyl acetate=19:1→14:1) to give ethyl 4-(2-{(3,5-bis-trifluoromethyl-benzyl)-[2-(4-methyl-pyridin-2-yl)-5-trifluoromethyl-benzyl]-amino}-pyrimidin-5-yloxy)-butyrate (85 mg). MS (m/z): 701 [M+H]+
