Procedure

A solution of (R)-tert-butyl 1-(5-chloro-3-(cyclopropanecarboxamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (462 mg, 1.06 mmol) in neat TFA (4 mL) was stirred at room temperature for 30 minutes and concentrated in vacuo. The oily residue obtained was dissolved in CH2Cl2 (1 mL) and treated with 2M HCl in ether (4 mL). The resulting precipitate was evaporated from CH3CN (4×10 mL) to provide (R)—N-(4-(3-aminopiperidin-1-yl)-5-chloro-1H-pyrrolo[2,3-b]pyridin-3-yl)cyclopropanecarboxamide hydrochloride (271 mg, 63% yield) as a solid. 1H NMR (400 MHz, (CD3)2SO) δ 11.79 (d, 1H), 9.65 (s, 1H), 8.25 (br s, 3H), 8.11 (s, 1H), 7.48 (d, 1H), 3.53-3.48 (m, 1H), 3.44-3.31 (m, 2H), 3.23-3.11 (m, 2H), 2.13-2.08 (m, 1H), 1.89-1.80 (m, 2H), 1.75-1.70 (m, 1H), 1.54-1.45 (m, 1140, 0.82 (d, 414). LCMS (APCI+) m/z 334 (M+H)+.
