実験手順

(R)-tert-Butyl piperidin-3-ylcarbamate (172 mg, 0.859 mmol) was added to N-(5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-5-methylnicotinamide (100 mg, 0.286 mmol) in n-BuOH (3 mL), and the reaction was stirred at 160° C. for 24 hours in a sealed tube. The reaction was concentrated to dryness, and then the residue was purified by chromatography (SP4, 25M, water/ACN 90/10 to 10/90, 30CV) to yield (R)-tert-butyl 1-(5-bromo-3-(5-methylnicotinamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (47 mg, 31.0% yield) as a solid.
