Procedure

A mixture of N-(5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)tetrahydrofuran-2-carboxamide (225 mg, 0.686 mmol), (R)-tert-butyl piperidin-3-ylcarbamate (412 mg, 2.06 mmol), and N-ethyl-N-isopropylpropan-2-amine (239 μL, 1.37 mmol) in n-BuOH (5 mL) was purged under N2 and stirred at 160° C. in a sealed tube for 16 hours. The solvent was then removed in vacuo, and the residue obtained was purified by C-18 reverse phase column chromatography (Biotage Flash 25M+; C-18) on Biotage SP4 unit eluting with a gradient of 15-90% CH3CN/water (25 CV) to provide tert-butyl (3R)-1-(5-bromo-3-(tetrahydrofuran-2-carboxamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (101 mg, 0.199 mmol, 29.0% yield) as a solid.
