Procedure

TFA (0.020 mL, 0.26 mmol) was added to (R)-tert-butyl 5-bromo-4-(3-(tert-butoxycarbonyl(methyl)amino)piperidin-1-yl)-3-(1-methyl-6-oxo-1,6-dihydropyridine-3-carboxamido)-1H-pyrrolo[2,3-b]pyridine-1-carboxylate (0.034 g, 0.052 mmol) in DCM (1 mL). The reaction mixture was stirred at room temperature for 1 hour. The solvent was removed. The residue was dissolved in DCM (1 mL), and 2N HCl in ether (3 mL) was added. The solid formed was collected to give (R)-N-(5-bromo-4-(3-(methylamino)piperidin-1-yl)-1H-pyrrolo[2,3-b]pyridin-3-yl)-1-methyl-6-oxo-1,6-dihydropyridine-3-carboxamide hydrochloride (25 mg, 91%) as a solid. 1H NMR (400 MHz, D2O) δ 8.34 (s, 1H), 8.30 (s, 1H), 7.97 (dd, 1H), 7.35 (s, 1H), 6.60 (d, 1H), 3.88 (m, 1H), 3.53 (s, 3H), 3.39 (m, 2H), 3.08 (m, 2H), 2.55 (s, 3H), 2.04 (m, 1H), 1.68 (m, 1H), 1.60 (m, 1H), 1.35 (m, 1H). LCMS (APCI+) m/z 459(M+H)+.
