tert-Butyl 4-(5-phenyl-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazine-1-carboxylate (1.10 g, 2.12 mmol) was placed in 1:1 THF:MeOH (20 mL). LiOH (3.54 mL, 10.6 mmol) was then added, and the reaction was heated to 50° C. for 1 hour. The reaction was cooled to room temperature, poured into water, and extracted with DCM (3×50 mL). The combined organic fractions were dried, filtered, concentrated, and then purified by column chromatography (500:5 DCM:MeOH) to give tert-butyl 4-(5-phenyl-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazine-1-carboxylate (0.40 g, 49.8% yield).
