Procedure

To a solution of N-{[1,6-diethyl-4-(tetrahydro-2H-pyran-4-ylamino)-1H-pyrazolo[3,4-b]pyridin-5-yl]methyl}-N′-[(6-fluoro-3′-formyl-3-biphenylyl)methyl]-1,3-benzenedicarboxamide (82 mg, 0.129 mmol) in DCM (2.58 mL) was added 4-piperidinecarbonitrile (14.21 mg, 0.129 mmol), NaBH(OAc)3 (41.0 mg, 0.193 mmol). This mixture was stirred at room temperature for 19 h. The reaction mixture was washed with H2O (1 mL), concentrated, purified using a Gilson HPLC (with 0.1% TFA), and basified with an amine cartridge to afford 0.0274 g (28%) of the title compound.
