Participants

Reaction Steps

N-[3,3-Dimethyl-1-(4-piperidylmethyl)indolin-6-yl][2-(1H-indazol-6-ylamino)(3-pyridyl)]carboxamide (140 mg, Example 41) was dissolved in 10 mL EtOH. Formaldehyde (10 mL, 37%) was added, followed by 100 mg of NaCNBH3. The mixture was stirred at RT overnight, and concentrated in vacuo. The crude was extracted between saturated NaHCO3 solution and EtOAc, the resulting organic layer was dried over MgSO4, filtered and concentrated in vacuo to afford a yellow solid. This material was further purified by preparative HPLC to yield a white solid. MS: 510 (M+1). Calc'd. for C30H35N7O—509.6.
