Reaction Steps

A mixture of N-(5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-3-fluoro-4-methoxybenzamide (300 mg, 0.785 mmol) and (R)-tert-butyl piperidin-3-ylcarbamate (472 mg, 2.36 mmol) in n-BuOH (3 mL) was stirred at 155° C. for 16 hours in a sealed tube. The reaction was then cooled to room temperature and concentrated in vacuo. The resulting residue was purified by reverse phase HPLC (Gilson) to provide (R)-tert-butyl 1-(5-bromo-3-(3-fluoro-4-methoxybenzamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (120 mg, 27% yield).
