Procedure

A mixture of N-(3-fluoro-4-(2-(2-morpholinoethylamino)pyridin-4-yloxy)phenyl)acetamide trifluoroacetate (40 mg), MeOH (1 mL), and 6 M HCl (0.2 mL) was heated at reflux for 3 h. The mixture was concentrated on a rotary evaporator and the residue was lyophilized to give the title compound (30 mg) as a white solid. 1H NMR (DMSO-d6) δ 11.12 (s, 1H), 8.85 (s, 1H), 7.95 (d, 1H, J=7 Hz), 7.08 (dd, 1H, J=9, 9 Hz), 6.65-6.63 (m, 2H), 6.54 (d, 1H, J=8 Hz), 6.31 (s, 1H), 3.90-3.75 (m 6H), 3.37-3.21 (m, 6H); MS(ESI−): m/z 373.14 (M+H)+.
