Reaction Steps
4-Chloro-3-methyl-5-phenyl-1-(phenyl sulfonyl)-1H-pyrrolo[2,3-b]pyridine (0.300 g, 0.784 mmol) and piperazine (0.675 g, 7.84 mmol) were placed in NMP (1 mL) and heated to 200° C. in a microwave for 1 hour. The reaction was then poured into water and extracted with MTBE. The combined organic fractions were dried, filtered, and concentrated to give the crude product 3-methyl-5-phenyl-1-(phenylsulfonyl)-4-(piperazin-1-yl)-1H-pyrrolo[2,3-b]pyridine (0.339 g, 100% yield), which was used without further purification.
