Procedure

N-(5-Bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-2-phenyl-propanamide (170 mg, 0.469 mmol) and (R)-tert-butyl piperidin-3-ylcarbamate (282 mg, 1.41 mmol) in s-BuOH (5 mL) were heated to 135° C. in a sealed tube for 24 hours. After cooling down, the residue was concentrated and purified by reverse phase chromatography (SP4, 25M, water/ACN 80/20->0/100, 30 CV) to yield tert-butyl (3R)-1-(5-bromo-3-(2-phenylpropanamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (142 mg, 55.8% yield) as a solid.
