Reaction Conditions

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 9 supra) (300 mg, 0.64 mmol) and (3-amino-3-phenyl-propyl)-carbamic acid tert-butyl ester (from Example 2 supra) (635 mg, 2.6 mmol) was heated at 140° C. with stirring for 2 hours. The resulting oil was purified by chromatography (silica gel, dichloromethane:methanol, 50:1) and then further purified by prep-HPLC to afford (4-{3-[2-(3-tert-butoxycarbonylamino-1-phenyl-propylamino)-pyrimidin-4-yl]-1H-pyrazolo[3,4-d]pyrimidin-6-ylamino}-cyclohexyl)-carbamic acid tert-butyl ester (30 mg, 7.1%).
