Procedure

N-(5-Bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-6-methylnicotinamide (260 mg, 0.745 mmol) and (R)-tert-butyl piperidin-3-ylcarbamate (447 mg, 2.23 mmol) in n-BuOH (3 mL) was heated to 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-(6-methylnicotinamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (12 mg, 3% yield).
