실험 절차
To 6-bromo-1H-indole (41.36 g, 211.0 mmol) in DMF (150 mL) at −78° C. was added chlorosulfonyl isocyanate (20 mL, 225 mmol). After complete addition, the mixture was allowed to warm to room temperature and stirred for 2 hrs. The reaction mixture was poured into ice (500 mL) and stirred for 30 minutes. The precipitate was collected on a filter and dried in a vacuum oven to give 6-bromo-1H-indole-3-carbonitrile as a light-beige solid (46.73 g, 100%).
