실험 절차

tert-Butyl 4-(3-methyl-5-phenyl-1-(phenyl sulfonyl)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazine-1-carboxylate (0.9 g, 1.69 mmol) was placed in 1:1 THF:MeOH (10 mL). 3M LiOH (aq., 5.63 mL, 16.9 mmol) was added, and the reaction was heated to 50° C. for 1 hour. The reaction was then cooled, added to water and extracted with DCM. The organics were dried, filtered and concentrated to give the crude product which was purified (500:3 to 500:8 DCM:MeOH) to give tert-butyl 4-(3-methyl-5-phenyl-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazine-1-carboxylate (0.390 g, 58.8% yield).
