Versuchsvorschrift

A sealed tube was charged with {4-[3-(3-bromo-phenyl)-1-trityl-1H-pyrazolo[3,4-d]pyrimidin-6-ylamino]-cyclohexyl}-carbamic acid tert-butyl ester (from Example 43 supra) (500 mg, 0.686 mmol), (3-amino-3-phenyl-propyl)-carbamic acid tert-butyl ester (from Example 2 supra) (258 mg, 1.03 mmol), DavePhos (54 mg, 0.137 mmol), K2CO3 (142 mg, 1.03 mmol), Pd2(dba)3 (31 mg, 0.0343 mmol) and 1,4-dioxane (14 mL). This mixture was stirred at 120° C. for 15 hours under an atmosphere of N2. The mixture was cooled and filtered; the filtrate was evaporated under reduced pressure to give the crude product. It was purified by chromatography (silica gel, 200-300 mesh, dichloromethane:MeOH, 200:1 to 50:1), then by prep-HPLC to give (4-{3-[3-(3-tert-butoxycarbonylamino-1-phenyl-propylamino)-phenyl]-1-trityl-1H-pyrazolo[3,4-d]pyrimidin-6-ylamino}-cyclohexyl)-carbamic acid tert-butyl ester. (Yield 63 mg, 10.2%).
