Vorschrift

tert-Butyl 4-(5-(3-fluorophenyl)-1-(phenyl sulfonyl)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazine-1-carboxylate (0.220 g, 0.410 mmol) was placed in 1:1 THF:MeOH (6 mL). 3M LiOH (0.683 mL, 2.05 mmol) was then added, and the reaction was stirred at 50° C. for 1 hour. The reaction was then cooled, added to water and extracted with DCM. The organic fractions were dried, filtered and concentrated to give the crude product tert-butyl 4-(5-(3-fluorophenyl)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazine-1-carboxylate (0.150 g, 92.29% yield), which was used without further purification.
