Procedure

To a solution of methyl indole-6-carboxylate (1.01 g) in dichloromethane (30 mL) were added aluminum chloride (1.53 g) and acetyl chloride (0.5 mL) at room temperature, and then the reaction mixture was stirred at room temperature for 1 hour. To the reaction mixture was added a saturated aqueous solution of sodium hydrogen carbonate, and extracted with ethyl acetate. The obtained organic layer was dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography to give the titled compound (625 mg) as a white solid.
