Procedure

NMP (4 mL), DIEA (2.47 g, 19.1 mmol), (R)-2-methoxypropanoic acid (1.42 g, 13.7 mmol), and BOP-Cl (3.48 g, 13.7 mmol) were added to a solution of crude (R)-tert-butyl 1-(3-amino-5-chloro-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (1.00 g, 2.73 mmol; Example 91, Step A) in NMP (3.3 mL). The reaction was stirred for 30 minutes. 3M LiOH (25 mL) was then added, and the reaction was stirred at room temperature for 18 hours. Water and DCM were added to the reaction mixture, and the layers were separated. The organic layer was dried, filtered, and concentrated. The resulting residue was purified by reverse phase chromatography (Biotage SP4, C-18 40M+, 5-95% water:ACN) to provide (R)-N-(4-((R)-3-aminopiperidin-1-yl)-5-chloro-1H-pyrrolo[2,3-b]pyridin-3-yl)-2-methoxypropanamide hydrochloride (655 mg, 56% yield) as a solid. 1H NMR (400 MHz, D2O) δ 8.03 (s, 1H), 7.50 (s, 1H), 3.99 (q, 1H), 3.58 (m, 1H), 3.46 (m, 1H), 3.37 (s, 3H), 3.29 (m, 1H), 3.15 (m, 1H), 3.00 (m, 1H), 2.09 (m, 1H), 1.80-1.60 (m, 2H), 1.51 (m, 1H), 1.34 (d, 3H). LCMS (APCI+) m/z 352.0 (M+H)+, Retention time=2.28 minutes (Method 3).
