Procedure

(R)-tert-Butyl 4-(3-(tert-butoxycarbonylamino)piperidin-1-yl)-3-isobutyramido-1H-pyrrolo[2,3-b]pyridine-1-carboxylate (0.010 g, 0.020 mmol; Example 81, Step B) 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 resulting residue was then purified by reverse phase chromatography (Biotage SP4, C-18 12M+, 0-50% ACN in 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 (R)—N-(4-(3-aminopiperidin-1-yl)-1H-pyrrolo[2,3-b]pyridin-3-yl)isobutyramide hydrochloride (0.002 g, 27% yield). LCMS (APCI+) m/z 302 (M+H)+.
