(4-Benzyloxy-5′-isopropyl-2′-methoxy-biphenyl-2-ylmethyl)-(3,5-bis-trifluoromethyl-benzyl)-(5-bromo-pyrimidin-2-yl)-amine (433 mg) is dissolved in toluene (5 ml) and thereto are added tris(dibenzylideneacetone)dipalladium (107 mg), sodium tert-butoxide (168 mg), 2-(di-tert-butylphosphino)biphenyl (69.4 mg) and morpholine (152 mg) and the mixture is stirred under nitrogen atmosphere at room temperature overnight. To the reaction solution is added a saturated brine, and the mixture is extracted with ethyl acetate. 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→2:1) to give (4-benzyloxy-5′-isopropyl-2′-methoxy-biphenyl-2-ylmethyl)-(3,5-bis-trifluoromethyl-benzyl)-(5-morpholin-4-yl-pyrimidin-2-yl)-amine (384 mg). MS (m/z): 751 [M+H]+
