tert-Butyl 2-methyl-2-(2-(6-methyl-1H-indazol-3-yl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamido)propylcarbamate (100 mg, 0.22 mmol) was added to a saturated solution of HCl gas in ethyl acetate (20 mL) and the mixture was stirred at room temperature for 3 hours. The solid obtained was filtered and washed with 5 mL of ethyl acetate to give N-(1-amino-2-methylpropan-2-yl)-2-(6-methyl-1H-indazol-3-yl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamide hydrochloride (25 mg, 32%) as a yellow solid. MS: (M+H)+=364; 1H NMR (300 MHz, DMSO): δ 13.45 (s, 1H), 12.96 (s, 1H), 9.19 (s, 1H), 8.47-8.40 (m, 2H), 8.12-8.10 (m, 3H), 7.46 (s, 1H), 7.12 (d, 1H, J=8.4 Hz), 3.84 (brs, 5H), 3.42 (d, 2H, J=4.8 Hz), 2.52 (s, 3H), 1.58 (s, 3H).
