Reaction Steps

2′-{[(3,5-Bis-trifluoromethyl-benzyl)-(5-morpholin-4-yl-pyrimidin-2-yl)-amino]-methyl}-4′-trifluoromethyl-biphenyl-2-ol (150 mg) is dissolved in N,N-dimethylformamide (3 ml) and thereto are added ethyl 4-bromobutyrate (50 μl) and potassium carbonate (47 mg), and the mixture is stirred at room temperature for 2 hours and at 80° C. for 2 hours. The reaction solution is cooled to room temperature, and thereto 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→4:1) to give ethyl 4-(2′-{[(3,5-bis-trifluoromethyl-benzyl)-(5-morpholin-4-yl-pyrimidin-2-yl)-amino]-methyl}-4′-trifluoromethyl-biphenyl-2-yloxy)-butyrate (163 mg). MS (m/z): 771 [M+H]+
