Procedure

To a solution of 4-[({[1,6-diethyl-4-(tetrahydro-2H-pyran-4-ylamino)-1H-pyrazolo[3,4-b]pyridin-5-yl]methyl}amino) carbonyl]benzoic acid (0.0452 g, 0.10 mmol) in DCM (1.0 mL) was added 1,1-dimethylethyl 4-{[5′-(aminomethyl)-2′-fluoro-3-biphenylyl]methyl}-1-piperazinecarboxylate (0.040 g, 0.10 mmol), HBTU (0.0569 g, 0.15 mmol), and Et3N (0.0281 mL, 0.20 mmol). This mixture was stirred at room temperature for 1 h, was concentrated and purified using a Gilson HPLC (with TFA). TFA (1 drop in each tube ˜12 mL) was added to Fractions containing product and solvent was concentrated using a GeneVav EZ-2 evaporator. The compound was purified again using a Gilson HPLC (with TFA) and evaporating the solvent using a GeneVav EZ-2 evaporator. Product was basified with an amine cartridge to afford 0.0284 g (39%) of the title compound.
