Versuchsvorschrift
tert-Butyl (R)-1-(5-chloro-3-((S)-2-methoxypropanamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (0.190 g, 0.420 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 concentrated to dryness. The resulting residue was then purified by reverse phase chromatography (Biotage SP4, C-18 25M+, 5-95 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 (S)—N-(4-((R)-3-aminopiperidin-1-yl)-5-chloro-1H-pyrrolo[2,3-b]pyridin-3-yl)-2-methoxypropanamide hydrochloride (0.100 g, 56% yield) as a solid. 1H NMR (400 MHz, D2O) 8.09 (s, 1H), 7.46 9s, 1H), 4.05-3.99 (q, 1H), 3.67-3.64 (m, 1H), 3.51-3.49 (m, 1H), 3.37 (s, 3H), 3.26-3.21 (m, 3H), 2.11-2.08 (m, 1H), 1.81-1.77 (m, 1H), 1.72-1.67 (m, 1H), 1.53-1.50 (m, 1H).
