Reaction Steps

N-(5-Bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-3-fluorobenzamide (306 mg, 0.869 mmol) and (R)-tert-butyl piperidin-3-ylcarbamate (522 mg, 2.61 mmol) were placed in n-BuOH (5 mL) and heated to 155° C. for 42 hours in a sealed tube. The reaction was cooled to room temperature and concentrated to dryness. The crude residue was purified by C-18 reverse phase flash chromatography (Biotage Horizon unit, C-18 25M column, 5-80% CH3CN/water gradient) to give (R)-tert-butyl 1-(5-bromo-3-(3-fluorobenzamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (125 mg, 27% yield).
