Reaction Steps

(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; Example 112, Step A) in NMP (2 mL), pyridine (1 mL) and propionyl chloride (0.365 g, 3.95 mmol) were 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+, 0-95% CH3CN/water) to give (R)-tert-butyl 1-(5-chloro-3-propionamido-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-yl(methyl)carbamate (0.160 g, 46% yield).
