NaH (0.10 g, 2.59 mmol) was then added, and the reaction was stirred for 20 minutes. Benzenesulfonyl chloride (0.304 mL, 2.38 mmol) was then added, and the reaction was stirred for 30 minutes at 0° C. Water (50 mL) was then added. The precipitate was filtered, washed with water, washed with ether, and dried to give 5-bromo-4-chloro-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine (0.8 g, 99.6% yield).
