Reaction Steps

N-{[1,6-Diethyl-4-(tetrahydro-2H-pyran-4-ylamino)-1H-pyrazolo[3,4-b]pyridin-5-yl]methyl}-N′-[(3′-formyl-6-methyl-3-biphenylyl)methyl]-1,3-benzenedicarboxamide (0.033 g, 0.05 mmol), (2R,6S)-2,6-dimethylpiperazine (0.00685 g, 0.06 mmol), and acetic acid (0.0036 g, 0.06 mmol) were combined in CH2Cl2 (2 mL). Sodium triacetoxyborohydride (0.0148 g, 0.07 mmol) was added and the mixture stirred overnight at room temperature. Solvents were concentrated, and the residue taken up in EtOAc, washed with 1N NaOH, brine, dried over anhydrous Na2SO4, filtered, and concentrated to give the crude product. The product was purified using a Gilson HPLC with a TFA system. The purified compound was taken up in EtOAc, washed 3× with 2.5 N NaOH, 1× with brine, dried over anhydrous Na2SO4, filtered, and concentrated to afford the title compound as a white solid. LC-MS m/z 757.2 (M+H)+, 1.37 min (ret time); mp 109-112° C. Analytical HPLC shows 99.8% purity, (ret time 10.205 min).
