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) (300 mg, 0.64 mmol) and [2-amino-2-(3-chloro-phenyl)-ethyl]-carbamic acid tert-butyl ester (from Example 4 supra) (686 mg, 2.5 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 crude [4-(3-{2-[2-tert-butoxycarbonylamino-1-(3-chloro-phenyl)-ethylamino]-pyrimidin-4-yl}-1H-pyrazolo[3,4-d]pyrimidin-6-ylamino)-cyclohexyl]-carbamic acid tert-butyl ester. (Yield 140 mg, 32.5%).
