Versuchsvorschrift

(R)-tert-Butyl 1-(5-bromo-3-(3-fluoropropanamido)-1H-pyrrolo [2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (50 mg, 0.103 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 residue was then purified by reverse phase chromatography (Biotage SP4, C-18 25M+, 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 the product (R)-N-(4-(3-aminopiperidin-1-yl)-5-bromo-1H-pyrrolo[2,3-b]pyridin-3-yl)-3-fluoro-propanamide hydrochloride (0.018 g, 38% yield) as a solid. 1H NMR (400 MHz, D2O) δ 8.24 (s, 1H), 7.29 (s, 1H), 4.77-4.73 (m, 1H), 4.66-4.65 m, 1H), 3.73-3.70 (m, 1H), 3.54-3.50 (m, 1H), 3.32-3.29 (m, 1H), 3.21-3.16 (m, 2H), 2.85-2.84 (m, 1H), 2.79-2.77 (m, 1H), 2.04-2.02 (m, 1H), 1.79-1.76 (m, 1H), 1.67-1.65 (m, 1H), 1.56-1.53 (m, 1H). LCMS (APCI+) m/z 384, 386 (M+H)+.
