Procedure

A mixture of (4-(2-(dimethylamino)ethyl)piperazin-1-yl)(3-(3-iodo-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazolo[3,4-b]pyridin-5-yl)phenyl)methanone (50 mg, 0.079 mmol), 5-fluoro-2-methoxyphenylboronic acid (20 mg, 0.118 mmol), [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II) complex with dichloromethane (7.9 mg, 0.10 mmol) and sodium carbonate (2M aqueous solution, 0.119 mL, 0.237 mmol) in acetonitrile (1 mL) was heated in a Personal microwave at 90° C. for 30 min. The resulting mixture was diluted with water and extracted with ethyl acetate. The organic layers were combined, dried over sodium sulfate, filtered and concentrated to dryness. Silica gel chromatography purification of the crude product afford (4-(2-(dimethylamino)ethyl)piperazin-1-yl)(3-(3-(5-fluoro-2-methoxyphenyl)-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazolo[3,4-b]pyridin-5-yl)phenyl)methanone as a light yellow oil. MS: m/z 633.3 (M+H+).
