Procedure

N-[(6-Chloro-3′-formyl-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), 1,1-dimethylethylhexahydro-1H-1,4-diazepine-1-carboxylate (0.012 g, 0.06 mmol), and acetic acid (0.0036 g, 0.06 mmol) were combined in 1,2-dichloroethane (2 mL), and the mixture stirred for thirty min. 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 protected product. This was treated with 10% TFA in CH2Cl2 for 3 h. 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 give the title compound as a white solid. LC-MS m/z 763.2 (M+H)+, 1.37 min (ret time); mp 116-119° C. Analytical HPLC shows 95.3% purity, (ret time 10.056 min).
