Procedure

Tert-butyl 3-[(2-{[(3,5-bis-trifluoromethyl-benzyl)-(5-bromo-pyrimidin-2-yl)-amino]-methyl}-4-trifluoromethyl-benzoyl)-ethyl-amino]-propionate (300 mg) is dissolved in toluene (5 ml), and thereto are added tris(dibenzylideneacetone)dipalladium (36 mg), 2-(di-tert-butylphosphino)biphenyl (47 mg), sodium tert-butoxide (57 mg) and morpholine (52 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=17:3→7:3) and further by silica gel column chromatography (hexane:ethyl acetate=4:1→3:2) to give tert-butyl 3-[(2-{[(3,5-bis-trifluoromethyl-benzyl)-(5-morpholin-4-yl-pyrimidin-2-yl)-amino]-methyl}-4-trifluoromethyl-benzoyl)-ethyl-amino]-propionate (13.3 mg). MS (m/z): 764 [M+H]+
