Reaction Steps

7-(3-Isopropenyl-2-oxo-2,3-dihydro-benzoimidazol-1-ylmethyl)-1,2,3-trimethyl-1H-indole-6-carboxylic acid methyl ester (100 mg. 0.25 mmol) was dissolved in MeOH (10 mL) and HCl (5 mL) solution at room temperature. The solution was heated to 60 C for 2 hours. The solution was cooled down and was extracted with EtOAc. The combined organic layer was dried with MgSO4 and was filtered. The filtrate was concentrated and the residue was purified by CombiFlash with 10% EtOAc in hexane as the eluent to afford the desirable product 1,2,3-Trimethyl-7-(2-oxo-2,3-dihydro-benzoimidazol-1-ylmethyl)-1H-indole-6-carboxylic acid methyl ester (85 mg, 94%) as a colorless oil.
