Procedure

Pyridine (1 mL) and cyclopropanecarbonyl chloride (0.413 g, 3.95 mmol) were added to (R)-tert-butyl 1-(3-amino-5-chloro-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-yl(methyl)carbamate (0.300 g, 0.790 mmol) in NMP (2 mL), and the reaction was stirred at room temperature for 1 hour. 3M aqueous LiOH (3 mL) was then added, and the reaction was stirred for 10 minutes. Water (10 mL) and DCM (10 mL) were then added, and the organic fraction was separated, dried, filtered, and concentrated. The crude residue was purified by reverse phase chromatography (Biotage SP4, C-18 25M+, 5-95% CH3CN/water) to give (R)-tert-butyl 1-(5-chloro-3-(cyclopropanecarboxamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-yl(methyl)carbamate (0.170 g, 48% yield).
