To a solution of N-[(3-bromo-4-fluorophenyl)methyl]-N′-{[1,6-diethyl-4-(tetrahydro-2H-pyran-4-ylamino)-1H-pyrazolo[3,4-b]pyridin-5-yl]methyl}-1,3-benzenedicarboxamide (0.166 g, 0.26 mmol) in 1,4-dioxane (3 mL) and H2O (1 mL) was added 1,1-dimethylethyl 4-{[3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]methyl}-1-piperidinecarboxylate (0.157 g, 0.390 mmol), Pd(Ph3P)4 (0.015 g, 0.013 mmol), and K2CO3 (0.144 g, 1.040 mmol). This mixture was heated in a microwave at 130° C. for 15 min. The organic layer was separated, filtered, concentrated, and purified with a Gilson HPLC (with 0.1% TFA). Before the sample was concentrated with GeneVav EZ-2, TFA (5 drops) was added to each tube (12 mL). The resultant mixture was concentrated, purified with a Gilson HPLC (with 0.1% TFA), concentrated, and basified with an amino cartridge to afford 0.0738 g (39%) of the title compound.
