Reaction Steps

To N-{[1,6-diethyl-4-(tetrahydro-2H-pyran-4-ylamino)-1H-pyrazolo[3,4-b]pyridin-5-yl]methyl}-N′-[(3′-formyl-3-biphenylyl)methyl]propanediamide (30 mg, 0.051 mmol) was added morpholine (4.49 mg, 0.051 mmol) followed by NaB(OAc)3H (36.4 mg, 0.172 mmol) and AcOH (4.91 μL, 0.086 mmol) in dimethyl sulfoxide (DMSO) (0.5 mL). The mixture was stirred overnight at room temperature. The reaction was quenched with saturated NaHCO3 and extracted with EtOAc (3×1 mL). Combined organic layers were washed with saturated NaCl, dried (Na2SO4) and concentrated. The crude products were redissolved in MeOH/DMSO (1/1) and purified using a Gilson HPLC (acidic conditions) and basified with an amine cartridge to afford 11.9 mg (34%) of the title compound. LC-MS m/z 654 (M+H)+.
