Procedure

m-CPBA (339 mg, 1.98 mmol) was added slowly to a solution of 4-{[3-(2-methylsulfanyl-pyrimidin-4-yl)-1H-pyrazolo[3,4-d]pyrimidin-6-ylamino]-methyl}-piperidine-1-carboxylic acid tert-butyl ester (from Example 14 supra) (450 mg, 0.99 mmol) in a mixture of dichloromethane and methanol (80 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, 15 g, 200-300 mesh, eluting with dichloromethane:methanol, 50:1 to 30:1) to afford 4-{[3-(2-methanesulfinyl-pyrimidin-4-yl)-1H-pyrazolo[3,4-d]pyrimidin-6-ylamino]-methyl}-piperidine-1-carboxylic acid tert-butyl ester. (Yield 150 mg, 32.3%).
