Reaction Steps

Piperazine (222 mg, 2.6 mmol) was added to 4-fluoro-5-isopropoxy-1H-pyrrolo[2,3-b]pyridine (50 mg, 0.26 mmol) in NMP (1 mL), and the reaction was heated to 200° C. for 1 hour under microwave irradiation. The reaction was concentrated to dryness under high vacuum and then purified by chromatography (SP4, 12+M, water/ACN 100/0→40/60, 20CV) to yield 5-isopropoxy-4-(piperazin-1-yl)-1H-pyrrolo[2,3-b]pyridine (33 mg, 49% yield) as an oil.
