Procedure

N-(5-Bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-2-(methylsulfonyl)acetamide (300 mg, 0.857 mmol) and (R)-tert-butyl piperidin-3-ylcarbamate (515 mg, 2.57 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-(2-(methylsulfonyl)acetamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (306 mg, 67.3% yield) as a solid.
