N-(5-Bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-3-methylbenzamide (210 mg, 0.60 mmol) and (R)-tert-butyl piperidin-3-ylcarbamate (360 mg, 1.8 mmol) in n-BuOH (3 mL) was stirred at 155° C. in a sealed tube. The reaction was then cooled to room temperature and concentrated to dryness. The crude residue was purified by reverse phase HPLC to give (R)-tert-butyl 1-(5-bromo-3-(3-methylbenzamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (150 mg, 47% yield).
