Reaction Steps

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 19 supra) (300 mg, 0.64 mmol) and 3-chlorobenzylamine (360 mg, 2.54 mmol) was heated at 130° C., with stirring for 2 hours. The resulting oil was purified by chromatography (silica gel, 10 g, 200-300 mesh, eluting with dichloromethane:methanol, 30:1 to 10:1) to afford (4-{3-[2-(3-chloro-b enzylamino)-pyrimidin-4-yl]-1H-pyrazolo[3,4-d]pyrimidin-6-ylamino}-cyclohexyl)-carbamic acid tert-butyl ester. (Yield 150 mg, 43.5%).
