A solution of (R)-tert-butyl 1-(3-amino-5-bromo-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-yl(methyl)carbamate (305 mg, 0.7188 mmol) in NMP (3 mL) was cooled to 0° C. and pyridine (1.5 mL) was added. Then the mixture was treated dropwise with cyclopropanecarbonyl chloride (195.7 μL, 2.156 mmol) and stirred at 0° C. for 30 minutes. 2M LiOH.H2O (4 mL) was then added, and the mixture was stirred at room temperature. After 48 hours, the mixture was diluted with EtOAc (100 mL) and washed with water (3×20 mL). The organic layer was separated, dried (MgSO4), filtered, and concentrated in vacuo. The residue was purified by reverse phase chromatography (Biotage SP4, C-18 40M+, 15-85% CH3CN/water, 35 CV) to provide (R)-tert-butyl 1-(5-bromo-3-(cyclopropanecarboxamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-yl(methyl)carbamate hydrochloride (127 mg, 36% yield) as a solid. LCMS (APCI+) m/z 492 (M+H)+.
