Procedure

A solution of (R)-tert-butyl 1-(5-bromo-3-(cyclopentanecarboxamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (65 mg, 0.13 mmol) in neat TFA (5 mL) was stirred at room temperature for 20 minutes. TFA was then removed in vacuo, and the residue was evaporated from CH2Cl2 (10 mL). The oily residue obtained was dissolved in CH2Cl2 (0.5 mL) and treated with 2M HCl in Et2O. After 30 minutes at room temperature, the solid formed was filtered, washed with additional Et2O and dried to provide (R)-N-(4-(3-aminopiperidin-1-yl)-5-bromo-1H-pyrrolo[2,3-b]pyridin-3-yl)cyclopentane carboxamide hydrochloride (38 mg, 62% yield) as a solid. 1H NMR (400 MHz, (CD3)2SO) δ 11.79 (s, 1H), 9.31 (s, 1H), 8.27 (br s, 1H), 8.23 (s, 1H), 7.59 (br s, 1H), 3.46-3.41 (m, 2H), 3.34-3.27 (m, 2H), 3.11-3.04 (m, 1H), 2.88-2.80 (m, 1H), 2.17-2.11 (m, 1H), 1.94-1.85 (m, 3H), 1.79-1.74 (m, 2H), 1.72-1.65 (m, 3H), 1.60-1.55 (m, 2H), 1.52-1.45 (m, 1H); LCMS (APCI+) m/z 406.0, 408.1 (M+H)+, Retention time=2.42 minutes (Method 2).
