A solution of 6-(1-(6-(1-ethoxyvinyl)-1H-[1,2,3]triazolo[4,5-b]pyrazin-1-yl)ethyl)-5,7-difluoroquinoline (100.0 mg, 0.24 mmol) and 3 N HCl (0.1 mL) in CH3OH (10 mL) was stirred at 50° C. for 2 hours. The solvent was removed under reduced pressure. The reaction mixture was concentrated in vacuo to give the title compound as yellow solid (80.0 mg, 96%). 1H-NMR (400 MHz, DMSO-d6) δ ppm 9.23 (s, 1H), 9.01 (dd, 1H), 8.53 (d, 2H), 7.76 (d, 1H), 7.64 (dd, 1H), 6.87 (q, 1H), 2.49 (s, 3H), 2.40 (d, 3H). LCMS (method A): [MH]+=355, tR=5.36 min.
