Reaction Steps

N-(5-Bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)quinoxaline-2-carboxamide (0.240 g, 0.621 mmol) and (R)-tert-butyl piperidin-3-ylcarbamate (0.373 g, 1.86 mmol) were placed in n-BuOH (3 mL) and heated to 155° C. for 48 hours in a sealed tube. The reaction was then cooled to room temperature and concentrated to dryness. The resulting residue was purified by reverse phase HPLC (5:75 water:ACN gradient, Gilson system) to give (R)-tert-butyl 1-(5-bromo-3-(quinoxaline-2-carboxamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (0.040 g, 11% yield).
