Procedure

A mixture of N-(5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-2-cyclopropylacetamide (204 mg, 0.654 mmol), (R)-tert-butyl piperidin-3-ylcarbamate (393 mg, 1.96 mmol), and triethylamine (182 μL, 1.31 mmol) in n-BuOH (5 mL) was processed as in Example 56. The crude was purified by C-18 reverse phase chromatography (Biotage 25M+) on Biotage SP4 unit eluting with a gradient of 15-85% CH3CN/water (25 CV) to provide (R)-tert-butyl 1-(5-bromo-3-(2-cyclopropylacetamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (85 mg, 26% yield) as a solid. LCMS (APCI+) m/z 492, 494 (M+H)+, Retention time=3.75 min (Method 2).
