実験手順

m-CPBA (428 mg, 2.4 mmol) was added slowly to a solution of 4-[3-(2-methylsulfanyl-pyrimidin-4-yl)-1H-pyrazolo[3,4-d]pyrimidin-6-ylamino]-piperidine-1-carboxylic acid tert-butyl ester (from Example 12 supra) (550 mg, 1.2 mmol) in a mixture of dichloromethane and methanol (100 mL, 1:1). The reaction mixture was stirred at room temperature for 20 minutes. The solvent was then removed under reduced pressure and the solid was purified by column chromatography (silica gel, 10 g, 200-300 mesh, eluting with dichloromethane:methanol, 50:1) to afford 4-[3-(2-methanesulfinyl-pyrimidin-4-yl)-1H-pyrazolo[3,4-d]pyrimidin-6-ylamino]-piperidine-1-carboxylic acid tert-butyl ester. (Yield 180 mg, 31.5%).
