Reaction Steps

(3,5-Bis-trifluoromethyl-benzyl)-(5-morpholin-4-yl-pyrimidin-2-yl)-[2-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-5-trifluoromethyl-benzyl]-amine (250 mg) is dissolved in 1,4-dioxane (5 ml) and thereto are added ethyl 4-chloro-2-trifluoromethyl-pyrimidine-5-carboxylate (140 mg), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium dichloromethane complex (30 mg) and cesium carbonate (177 mg), and the mixture is stirred under nitrogen atmosphere at 80° C. overnight. The reaction solution is cooled to room temperature, and thereto are added water and ethyl acetate and the insoluble materials are removed by filtration through Celite™. The filtrate 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→4:1) to give ethyl 4-(2-{[(3,5-bis-trifluoromethyl-benzyl)-(5-morpholin-4-yl-pyrimidin-2-yl)-amino]-methyl}-4-trifluoromethyl-phenyl)-2-trifluoromethyl-pyrimidine-5-carboxylate (199 mg). MS (m/z): 783 [M+H]+
