実験手順

(R)-tert-Butyl 1-(5-bromo-3-(2-cyanoacetamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (0.050 g, 0.10 mmol) was placed in DCM (3 mL) at room temperature. TFA (1 mL) was then added. The reaction was stirred at room temperature for 1 hour and then concentrated to dryness. The resulting residue was then purified by reverse phase chromatography (Biotage SP4, C-18 25M+, 5-50% CH3CN/water). The resulting product was next dissolved in minimal DCM (with MeOH to aid solubility) and added to a stirring solution of 1M HCl in ether. The resulting solid was filtered, washed with ether and dried to give (R)-N-(4-(3-aminopiperidin-1-yl)-5-bromo-1H-pyrrolo[2,3-b]pyridin-3-yl)-2-cyano acetamide hydrochloride (0.035 g, 74% yield) as a solid. 1H NMR (400 MHz, D2O) δ 8.24 (s, 1H), 7.32 (s, 1H), 3.83 (s, 2H), 3.73-3.70 (m, 1H), 3.56-3.54 (m, 1H), 3.32-3.29 (m, 1H), 3.24-3.13 (m, 2H), 2.10-2.07 (m, 1H), 1.83-1.79 (m, 1H), 1.67-1.55 (m, 2H). LCMS (APCI+) m/z 377, 379 (M+H)+.
