Reaction Steps

N-(5-Bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-1-methylcyclopropanecarboxamide (464 mg, 1.49 mmol) and (R)-tert-butyl piperidin-3-ylcarbamate (298 mg, 1.49 mmol) in s-BuOH (5 mL) were heated to 135° C. in a sealed tube for 24 hours. After cooling down, the residue was concentrated and purified by reverse phase chromatography (SP4, 25M, water/ACN 80/20→0/100, 30 CV) to yield (R)-tert-butyl 1-(5-bromo-3-(1-methylcyclopropanecarboxamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (382 mg, 52.2% yield) as a solid.
