Reaction Steps

(S)-N-(5-Bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-2-hydroxypropanamide (0.040 g, 0.13 mmol), (R)-tert-butyl pyrrolidin-3-ylcarbamate (0.074 g, 0.40 mmol) and DIEA (0.069 mL, 0.40 mmol, d 0.742) were placed in n-BuOH (1 mL) and heated to 135° C. for 8 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+, 0-60% CH3CN/water) to give tert-butyl (R)-1-(5-bromo-3-((S)-2-hydroxypropanamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)pyrrolidin-3-ylcarbamate (0.040 g, 65% yield).
