Reaction Steps

A mixture of 3,3-dimethyl-1-{4-[(1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-benzimidazol-2-yl)oxy]phenyl}-1,3-dihydro-2H-pyrrolo[2,3-b]pyridin-2-one (258 mg) and 2N HCl in EtOH (5 mL) in EtOH (5 mL) was stirred at 60° C. for 10 h. After cooling to room temperature, the solvent was removed. The residue was recrystallized from EtOH-AcOEt to give 1-[4-(1H-benzimidazol-2-yloxy)phenyl]-3,3-dimethyl-1,3-dihydro-2H-pyrrolo[2,3-b]pyridin-2-one dihydrochloride (152 mg).
