Versuchsvorschrift

(R)-tert-Butyl 1-(5-bromo-3-(cyclopropanecarboxamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (110 mg, 0.230 mmol) in TFA (5 mL) was stirred at room temperature for 30 minutes, and the TFA was removed in vacuo. The oily residue obtained was dissolved in CH2Cl2 (1 mL), and 2M HCl in Et2O was added. The mixture was stirred at ambient temperature for 30 minutes. The solid formed was filtered and triturated with CH3CN to provide (R)—N-(4-(3-aminopiperidin-1-yl)-5-bromo-1H-pyrrolo[2,3-b]pyridin-3-yl)cyclopropanecarboxamide hydrochloride (70 mg, 67% yield). 1H NMR (400 MHz, (CD3)2SO) δ 11.82 (s, 1H), 9.65 (s, 1H), 8.26 (br s, 3H), 8.22 (s, 1H), 7.47 (s, 1H), 3.46-3.40 (m, 3H), 3.31-3.23 (m, 1H), 3.12-3.06 (m, 1H), 2.15-2.09 (m, 1H), 1.87-1.80 (m, 2H), 1.76-1.69 (m, 1H), 1.53-1.43 (m, 1H), 0.83-0.81 (m, 4H); LCMS (APCI+) m/z 378.8, 379.9 (M+H)+, Retention time=2.18 minutes (Method 2).
