Reaction Steps
Ethyl 4-{2-[(3,5-bis-trifluoromethyl-benzyl)-(2-trifluoromethanesulfonyloxy-5-trifluoromethyl-benzyl)-amino]-pyrimidin-5-yloxy}-butyrate (200 mg) is dissolved in 1,4-dioxane (3 ml), and thereto are added phenyl boronic acid (64 mg), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium dichloromethane complex (22 mg) and cesium carbonate (172 mg), and the mixture is stirred under nitrogen atmosphere at 80° C. overnight. 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 NH-silica gel column chromatography (hexane:ethyl acetate=19:1→17:3) to give ethyl 4-{2-[(3,5-bis-trifluoromethyl-benzyl)-(4-trifluoromethyl-biphenyl-2-ylmethyl)-amino]-pyrimidin-5-yloxy}-butyrate (192 mg). MS (m/z): 686 [M+H]+
