Procedure

(S)—N-(5-Bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-2-methoxypropanamide (120 mg, 0.38 mmol) and (R)-tert-butyl piperidin-3-ylcarbamate (228 mg, 1.14 mmol) in n-BuOH (4 mL) were heated to 160° C. for 18 hours in a sealed tube. After concentration, the residue was purified by C-18 reverse phase flash chromatography (Biotage SP4 unit, C-18 25M column, 10-90% CH3CN/water gradient; 30 CV) to yield tert-butyl (R)-1-(5-bromo-3-((S)-2-methoxypropanamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (84 mg, 45% yield) as a solid.
