Procedure

To a stirred solution of [3-(3-bromo-phenyl)-1-(2-trimethylsilanyl-ethoxymethyl)-1H-pyrazolo[3,4-d]pyrimidin-6-yl]-(2-morpholin-4-yl-ethyl)-amine (from Example 40 supra) (250 mg, 0.468 mmol), thiophen-2-yl-methylamine (80 mg, 0.70 mmol), DavePhos (30 mg, 0.076 mmol) and t-BuONa (70 mg, 0.73 mmol) in 1,4-dioxane (10 mL), Pd2(dba)3 (42 mg, 0.073 mmol) was added in one portion under N2 atmosphere. The resultant mixture was stirred at 100° C. for 4 hours. 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, 100:1, v/v) to give (2-morpholin-4-yl-ethyl)-[3-{3-[(thiophen-2-ylmethyl)-amino]-phenyl}-1-(2-trimethylsilanyl-ethoxymethyl)-1H-pyrazolo[3,4-d]pyrimidin-6-yl]-amine. (Yield 170 mg, 64.2%).
