Reaction Steps

5-Cyanoindole (0.500 g, 3.52 mmol) was dissolved in DMF (25 mL), and sodium hydroxide (0.493 g, 8.79 mmol) and iodine (0.902 g, 3.55 mmol) were added thereto, then the mixture was stirred at room temperature for 25 minutes. A saturated aqueous sodium thiosulfate solution was added to the mixture, and the precipitated solid was filtered off to give 5-cyano-3-iodoindole (0.707 g, 75%).
