(3,5-Bis-trifluoromethyl-benzyl)-(5-bromo-pyrimidin-2-yl)-amine (315 mg) and 4-benzyloxy-2-chloromethyl-5′-isopropyl-2′-methoxy-biphenyl (300 mg) are dissolved in N,N-dimethylformamide (5 ml) and thereto is added sodium hydride (60%) (40.9 mg) under ice-cooling, and the mixture is stirred at room temperature overnight. Thereto are added a saturated aqueous ammonium chloride solution 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=1:0→97:3) to give (4-benzyloxy-5′-isopropyl-2′-methoxy-biphenyl-2-ylmethyl)-(3,5-bis-trifluoromethyl-benzyl)-(5-bromo-pyrimidin-2-yl)-amine (458 mg). MS (m/z): 744/746 [M+H]+
