Reaction Steps

To a solution of 1-(1,2-dimethyl-1H-indol-7-ylmethyl)-1,3-dihydro-benzimidazol-2-one (170 mg, 0.58 mmol) in DMF (3.0 mL) are added methyl acrylate (0.06 mL, 0.6 mmol) and 40% benzyltrimethyl ammonium hydroxide in MeOH (0.06 mL, 0.15 mmol). The resulting mixture is stirred at room temperature for 18 h after which time water (20 mL) was added. The mixture is extracted with EtOAc (3×50 mL) and the organic layers are combined, dried over MgSO4 and concentrated to give crude product. Purification by flash column chromatography using 20-50% EtOAc in Hexanes affords 90 mg (41%) of 3-[3-(1,2-dimethyl-1H-indol-7-ylmethyl)-2-oxo-2,3-dihydro-benzimidazol-1-yl]-propionic acid methyl ester.
