Reaction Steps

N-{[3′-(Chloromethyl)-6-fluoro-3-biphenylyl]methyl}-N′-{[1,6-diethyl-4-(tetrahydro-2H-pyran-4-ylamino)-1H-pyrazolo[3,4-b]pyridin-5-yl]methyl}-1,3-benzenedicarboxamide (0.034 g, 0.05 mmol) and 1-(1-methylethyl)piperazine (0.0325 g, 0.25 mmol) were combined in THF (1 mL) and microwaved at 150° C. for 1 h. The mixture was purified using a Gilson HPLC with a TFA system followed by passing product though a quaternary ammonium hydroxide cartridge to give the free base, the title compound, as a white solid. LC-MS m/z 774.8 (M+H)+, 1.46 min (ret time); mp 165-169° C. Analytical HPLC shows 100% purity, (ret time 10.233 min).
