Versuchsvorschrift

A solution of N-({3-[(cyclopentylmethyl)(ethyl)amino]-6-methoxypyridin-2-yl}methyl)-5-[2-(methylthio)ethoxy]pyrimidin-2-amine (168 mg, 0.39 mmol) in N,N-dimethylformamide (1 mL) stirred under ice cooling was added with sodium hydride (50% in oil, 24 mg, 1.4 mmol), and the mixture was stirred at 50° C. for 30 minutes. The reaction mixture was cooled to −78° C., added with a solution of 1-bromo-[3,5-bis(trifluoromethyl)phenyl]ethane (250 mg, 0.78 mmol) obtained in Step 2 in N,N-dimethylformamide (0.5 mL), and the mixture was stirred for 12 hours with warming to room temperature. The reaction mixture was added with water, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous sodium sulfate, and then concentrated under reduced pressure, and the resulting residue was purified by silica gel column chromatography (hexane:ethyl acetate=3:1) to obtain the target compound, N-{1-[3,5-bis(trifluoromethyl)phenyl]ethyl}-N-({3-[(cyclopentylmethyl)(ethyl)amino]-6-methoxypyridin-2-yl}methyl)-5-[2-(methylthio)ethoxy]pyrimidin-2-amine (88.1 mg, 34%), as pale yellow oil.
