Reaction Steps

4-Fluoro-5-(2-fluorophenyl)-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine (0.200 g, 0.540 mmol) and tert-butyl piperazine-1-carboxylate (0.121 g, 0.648 mmol) were placed in NMP (2 mL). The reaction was then placed in the microwave and heated to 160° C. for 1 hour. The reaction was then cooled, poured into water and extracted with ether. The combined organic fractions were dried, filtered, and concentrated to give a crude oil that was purified by column chromatography (3:1 hexane:EtOAc) to give tert-butyl 4-(5-(2-fluorophenyl)-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazine-1-carboxylate (0.102 g, 35.2% yield).
