Procedure

To N-{[3-bromo-4-(methyloxy)phenyl]methyl}-N′-{[1,6-diethyl-4-(tetrahydro-2H-pyran-4-ylamino)-1H-pyrazolo[3,4-b]pyridin-5-yl]methyl}-2,6-pyridinedicarboxamide (40.46 g, 62.2 mmol) in a 2 L 3-neck flask was added 1,1-dimethylethyl 4-{[3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]methyl}-1-piperidinecarboxylate (24.96 g, 62.2 mmol) and 1,4-dioxane (700 mL). Then potassium carbonate (25.8 g, 187 mmol) and water (233 mL) were added followed by tetrakis(triphenylphosphine)palladium(0) (3.59 g, 3.11 mmol) and the mixture was then stirred at 100° C. under nitrogen with conventional heating. After 2 h the reaction was cooled and the mixture was partitioned between ethyl acetate and water and the aqueous layer extracted well with ethyl acetate. The combined organics were washed with water, brine, dried (MgSO4), filtered and evaporated to give 59.49 g (113%) of a brown foam. The crude product was purified on a 750 g Companion XL silica cartridge, eluting with 0-100% of {1% MeOH in ethyl acetate} in dichloromethane over 14 column volumes. This gave 25.38 g (48%) of a pale beige foam that the lab HPLC showed to be 97.23% pure with a retention time of 2.60 min. LC-MS m/z 845 (M+H)+, 3.02 min (ret time).
