Conditions

Temperature: 130 °C

Procedure

The mixture of {4-[3-(2-methanesulfinyl-pyrimidin-4-yl)-1H-pyrazolo[3,4-d]pyrimidin-6-ylamino]-cyclohexyl}-carbamic acid tert-butyl ester (from Example 9 supra) (140 mg, 0.3 mmol) and 3-fluorobenzylamine (148 mg, 1.2 mmol) was heated at 130° C. with stirring for 2 hours. The resulting oil was purified by chromatography (silica gel, 8 g, 200-300 mesh, eluting with dichloromethane:methanol, 50:1 to 30:1) to afford (4-{3-[2-(3-fluoro-benzylamino)-pyrimidin-4-yl]-1H-pyrazolo[3,4-d]pyrimidin-6-ylamino}-cyclohexyl)-carbamic acid tert-butyl ester. (Yield 110 mg, 69.6%).
