Versuchsvorschrift

A solution of 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 (82 mg, 0.12 mmol) obtained in Example 1 in acetonitrile (3 mL) was added with molybdenum dioxide dichloride (3.6 mg, 0.018 mmol) and 30% aqueous hydrogen peroxide (55 mg, 0.49 mmol), and the mixture was stirred at room temperature for 23 hours. The reaction mixture was added with saturated aqueous sodium sulfite, and the mixture was extracted with chloroform. Then, the organic layer was washed with saturated brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The resulting residue was purified by preparative silica gel thin layer chromatography (hexane:acetone=3:2) to obtain N-{1-[3,5-bis(trifluoromethyl)phenyl]ethyl}-N-({3-[(cyclopentylmethyl)(ethyl)amino]-6-methoxypyridin-2-yl}methyl)-5-[2-(methylsulfinyl)ethoxy]pyrimidin-2-amine (compound of Example 2, 8.4 mg, 10%) as yellow oil, and N-{1-[3,5-bis(trifluoromethyl)phenyl]ethyl}-N-({3-[(cyclopentylmethyl)(ethyl)amino]-6-methoxypyridin-2-yl}methyl)-5-[2-(methylsulfonyl)ethoxy]pyrimidin-2-amine (compound of Example 3, 59.5 mg, 69%) as pale yellow oil.
