Reaction Steps

5-Bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridine (5.3 g, 24.7 mmol) was placed in DMF (53 mL) at 0° C. NaH (1.18 g, 29.6 mmol) was then added and stirred for 20 minutes. Benzenesulfonyl chloride (3.47 mL, 27.1 mmol) was then added next, and the reaction was stirred at 0° C. for 30 minutes. Water was then added, and the resulting solid was filtered and dried. The crude solid was then triturated in 1:1 hexane:EtOAc to give 5-bromo-4-fluoro-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine (5.2 g, 59.4% yield).
