반응 단계

trans-N-(5-Bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-2-phenylcyclopropanecarboxamide (500 mg, 1.34 mmol) and (R)-tert-butyl piperidin-3-ylcarbamate (1338 mg, 6.68 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 (R)-1-(5-bromo-3-(trans-2-phenyl cyclopropanecarboxamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (359 mg, 48.5% yield) as a solid.
