Versuchsvorschrift

(S)—N-(5-Bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-2-methoxypropanamide (0.6 g, 1.9 mmol), (R)-tert-butyl pyrrolidin-3-ylcarbamate (1.1 g, 5.7 mmol), and DIEA (0.99 mL, 5.7 mmol) were placed in n-BuOH (4 mL) and heated at 135° C. for 12 hours. The reaction was cooled to room temperature, concentrated, and purified by silica gel chromatography (500:15 DCM:MeOH) to give tert-butyl (R)-1-(5-bromo-3-((S)-2-methoxypropanamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)pyrrolidin-3-ylcarbamate (0.55 g, 60% yield).
