Procedure

N-(5-Bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-2-hydroxy-acetamide (0.200 g, 0.694 mmol), (R)-tert-butyl piperidin-3-ylcarbamate (0.417 g, 2.08 mmol), and DIEA (0.363 mL, 2.08 mmol) were placed in n-BuOH (2 mL) and heated to 140° C. for 18 hours. The reaction was then cooled to room temperature and concentrated to dryness. The resulting residue was purified by reverse phase chromatography (Biotage SP4, C-18 25M+, 5-75 CH3CN/water) to give (R)-tert-butyl 1-(5-bromo-3-(2-hydroxyacetamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (0.220 g, 68% yield).
