実験手順

N-[(6-Cyano-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 (108 mg, 0.000161 mol) in DCM (4 mL) and (2R,6S)-2,6-dimethylpiperazine (26.7 mg, 0.00023 mol) were mixed with sodium triacetoxyborohydride (68.3 mg, 0.00032 mol) and AcOH (11.6 mg, 11 μL). This solution was stirred overnight at room temperature. LC-MS showed that the reaction was complete. The reaction was quenched with sat. aq. NaHCO3, then extracted with DCM (2×). The combined organic extracts were washed with sat. aq. NaCl, dried (Na2SO4) and concentrated to a glassy foam (122.9 mg). Purification was carried out on Gilson instrument with acetonitrile-water (0.1% TFA) gradient; C18-RP column. Fractions containing the clean desired product were combined; diluted with EtOAc; washed with sat. aq. NaHCO3; and the aq. phase was back-extracted with EtOAc. Combined organic layers were washed with sat. aq. NaCl and dried (Na2SO4) and concentrated to a residue. It was taken up in a small amount of DCM and transferred to a vial and pumped down to afford the title compound as a white solid [62.3 mg (51%)]. LC-MS m/z 769.7 (M+H)+.
