실험 절차

(R)-tert-Butyl 1-(5-chloro-3-(cyclopropanecarboxamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-yl(methyl)carbamate (0.150 g, 0.335 mmol) was placed in DCM (3 mL) at room temperature. TFA (1 mL) was then added, and the reaction was stirred at room temperature for 1 hour and concentrated to dryness. The resulting residue was then purified by reverse phase chromatography (Biotage SP4, C-18 12M+, 0-50% CH3CN/water). The resulting product was next dissolved in minimal DCM (with MeOH to aid solubility) and added to a stirred solution of 1M HCl in ether. The resulting solid was filtered, washed with ether and dried to give (R)—N-(5-chloro-4-(3-(methylamino)piperidin-1-yl)-1H-pyrrolo[2,3-b]pyridin-3-yl)cyclopropanecarboxamide hydrochloride (0.120 g, 85% yield) as a solid. 1H NMR (400 MHz, D2O) δ 8.12 (s, 1H), 7.27 (s, 1H), 3.87-3.84 (m, 1H), 3.42-3.37 (m, 2H), 3.22-3.17 (m, 2H), 2.60 (s, 3H), 2.18-2.15 (m, 1H), 1.82-1.67 (m, 3H), 1.56-1.53 (m, 1H), 0.91-0.80 (m, 4H). LCMS (APCI+) m/z 348 (M+H)+.
