Procedure

(3,5-Bis-trifluoromethyl-benzyl)-(5-bromo-pyrimidin-2-yl)-(2-fluoro-5-trifluoromethyl-benzyl)-amine (300 mg) is dissolved in toluene (5 ml) and tris(dibenzylideneacetone)dipalladium (48 mg), 2-(di-tert-butylphosphino)biphenyl (62 mg), sodium tert-butoxide (75 mg) and morpholine (68 μl) and the mixture is stirred under nitrogen atmosphere at room temperature overnight. To the reaction solution are added a saturated aqueous sodium bicarbonate 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 NH-silica gel column chromatography (hexane:ethyl acetate=19:1→9:1) to give (3,5-bis-trifluoromethyl-benzyl)-(2-fluoro-5-trifluoromethyl-benzyl)-(5-morpholin-4-yl-pyrimidin-2-yl)-amine (176 mg). MS (m/z): 583 [M+H]+
