N-(5-Bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-2-methoxyacetamide (100 mg, 0.3 mmol) and (R)-tert-butyl piperidin-3-ylcarbamate (199 mg, 1.0 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 (R)-tert-butyl 1-(5-bromo-3-(2-methoxyacetamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (51 mg, 32% yield) as a solid.
