Methyl iodide → 3,3-dimethyl-1-{4-[(1-methyl-1H-benzimidazol-2-yl)oxy]phenyl}-1,3-dihydro-2H-pyrrolo[2,3-b]pyridin-2-one

Participants

Reaction Steps

NaH (17.28 mg) was added to a solution of 1-[4-(1H-benzimidazol-2-yloxy)phenyl]-3,3-dimethyl-1,3-dihydro-2H-pyrrolo[2,3-b]pyridin-2-one (40 mg) and MeI (10.13 μl) in DMF(1 mL) at room temperature. The mixture was stirred at room temperature under a dry atmosphere (CaCl2 tube) for 1 h. The reaction mixture was diluted with MeOH and concentrated in vacuo. The residue was purified by column chromatography (NH silica gel, eluted with 0%-50% EtOAc in hexane) to give 3,3-dimethyl-1-{4-[(1-methyl-1H-benzimidazol-2-yl)oxy]phenyl}-1,3-dihydro-2H-pyrrolo[2,3-b]pyridin-2-one (35 mg) as white crystals.
