N-(4-Chloro-5-(trifluoromethyl)-1H-pyrrolo[2,3-b]pyridin-3-yl)pyrazine-2-carboxamide (0.230 g, 0.673 mmol) and (R)-tert-butyl piperidin-3-ylcarbamate (0.404 g, 2.02 mmol) were placed in n-BuOH (3 mL) and heated to 155° C. for 18 hours in a sealed tube. The reaction was then cooled to room temperature and concentrated to dryness. The resulting residue was purified by C-18 reverse phase flash chromatography (Biotage SP4 unit, C-18 25M column, 5-75% CH3CN/water gradient; 25 CV) to give (R)-tert-butyl 1-(3-(pyrazine-2-carboxamido)-5-(trifluoromethyl)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (0.120 g, 35% yield).
