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}-1,3-benzenedicarboxamide (0.033 g, 0.05 mmol), 1,1-dimethylethyl (2S)-2-methyl-4-{[3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]methyl}-1-piperazinecarboxylate (0.0316 g, 0.076 mmol), potassium carbonate (0.021 g, 0.15 mmol), and tetrakis(triphenylphosphine)palladium(0) (0.0029 g, 0.0025 mmol) were combined in dioxane (1.5 mL) and water (0.5 mL). The mixture was microwaved at 150° C. for 30 min. The reaction mixture was then diluted with EtOAc and washed with H2O. The organic phase was dried over anhydrous Na2SO4, filtered and concentrated. This was taken up in 10% TFA/CH2Cl2 and stirred at room temperature for 3 h. The solvents were pumped off and the crude product was purified using a Gilson HPLC with a TFA system. The purified compound was taken up in EtOAc, washed with 2.5 N NaOH, with brine, dried over anhydrous Na2SO4, filtered, and concentrated to give the title compound a white solid. LC-MS m/z 759.2 (M+H)+, 1.35 min (ret time); mp 110-112° C. Analytical HPLC shows 100% purity, (ret time 9.95 min).
