To a stirred solution of N-(1-(tert-butyldimethylsilyloxy)-2-methylpropan-2-yl)-2-(6-methyl-1-(2-morpholino-2-oxoethyl)-1H-indazol-3-yl)-5-trityl-5H-pyrrolo[3,2-b]pyrazine-7-carboxamide (100 mg, 0.118 mmol) in dioxane (40 mL) was bubbled HCl gas until saturation and then stirred at room temperature for 16 hours. The mixture was concentrated and the residue was triturated with methanol (1 mL), solvent decanted and solid dried to afford N-(1-hydroxy-2-methylpropan-2-yl)-2-(6-methyl-1-(2-morpholino-2-oxoethyl)-1H-indazol-3-yl)-5H-pyrrolo[3,2-b]pyrazine-7-carboxamide hydrochloride (44 mg, 71%) as a yellow solid. LCMS: (M+H)+=492; 1H NMR (300 MHz, DMSO+D2O): δ 9.07 (s, 1H), 8.44 (d, 1H, J=8.4 Hz), 8.36 (s, 1H), 7.45 (s, 1H), 7.15 (d, 1H, J=8.4 Hz), 5.55 (s, 2H), 3.72-3.65 (m, 8H), 3.47 (brs, 2H), 2.53 (s, 3H), 2.36 (brs, 2H), 1.46 (s, 6H).
