실험 절차

A sealed tube was charged with N-(5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-2,2-difluorocyclopropanecarboxamide (150 mg, 0.449 mmol), (R)-tert-butyl piperidin-3-ylcarbamate (270 mg, 1.35 mmol), N-ethyl-N-isopropylpropan-2-amine (235 μL, 1.35 mmol) and n-BuOH (3 mL). Then N2 was bubbled through the mixture for 5 minutes. The tube was sealed under N2 and stirred at 120° C. for 5 hours and then at 130° C. for 48 hours. The mixture was concentrated in vacuo, and the residue was purified by reverse phase chromatography (Biotage SP4, C-18 25M+, 15-85% CH3CN/water, 23 CV) to yield tert-butyl (3R)-1-(5-bromo-3-(2,2-difluorocyclopropanecarboxamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (81 mg, 35% yield) as a solid. LCMS (APCI+) m/z 514.1, 516.1 (M+H)+.
