Reaction Steps
4-Chloro-5-phenyl-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine (1.70 g, 4.61 mmol) was placed in 1:1 THF:water (30 mL). 3M LiOH (aq., 15.4 mL, 46.1 mmol) was then added, and the reaction was heated to 65° C. for 18 hours. The reaction was cooled to room temperature, diluted with DCM (50 mL) and poured into water. The organic fraction was dried, filtered, and concentrated to give the crude product 4-chloro-5-phenyl-1H-pyrrolo[2,3-b]pyridine (1.01 g, 95.8% yield), which was used without further purification.
