Reaction Steps

(R)-tert-Butyl piperidin-3-ylcarbamate (205 mg, 1.0 mmol) was added to N-(5-ethoxy-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)cyclopropanecarboxamide (90 mg, 0.34 mmol) in n-butanol (2 mL). The reaction was stirred at 160° C. for 24 hours in a sealed tube. After cooling down and concentration, the residue was purified by reverse phase chromatography (Biotage SP4, C-18 25M+, water/ACN 90/10→10/90, 30CV) to yield (R)-tert-butyl 1-(3-(cyclopropanecarboxamido)-5-ethoxy-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (39 mg) as a solid.
