Versuchsvorschrift

To a mixture of tert-butyl 1-(5-(5-bromo-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazolo[3,4-c]pyridin-3-yl)pyridin-3-yl)piperidin-4-ylcarbamate (45.0 mg, 0.0807 mmol), 3-Pyridylboronic acid (29.8 mg, 0.242 mmol) and 1,1′-Bis(diphenylphosphino)ferrocenepalladium (II) chloride (9.888 mg, 0.01211 mmol) in Acetonitrile (1.01 mL, 19.4 mmol) was added 1.0 M of Potassium acetate in Water (0.121 mL) and 1.0 M of Sodium carbonate in Water (0.121 mL). The reaction mixture was irradiated in microwave at 125° C. for 20 min. The reaction was filtered thru celite. The filtrate was washed H2O and brine. The organic layer was dried with Na2SO4, filtered, and concentrated to give tert-butyl 1-(5-(5-(pyridin-3-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazolo[3,4-c]pyridin-3-yl)pyridin-3-yl)piperidin-4-ylcarbamate.
