Procedure
2-(2-Methanesulfinyl-pyrrolo[2,1-f][1,2,4]triazin-7-yl)-phenol (0.68 g, 2.5 mmol), 2-Bromoacetamide (0.414 g, 3.00 mmol), Potassium carbonate (0.7049 g, 5.100 mmol), and Acetonitrile (20 mL, 500 mmol) were combined in a round bottom flask and heated at 60° C. for 19 hours. The solid was filtered through Celite and washed with DCM. The filtrate was concentrated and purified via normal phase silica gel chromatography eluting with dichloromethane /methanol to yield a yellow solid, 2-[2-(2-Methanesulfinyl-pyrrolo[2,1-f][1,2,4]triazin-7-yl)-phenoxy]-acetamide (719 mg, 87%). LCMS: m/z=331.16 (M+H+); 1H NMR (400 MHz, DMSO-d6) δ 9.31 (s, 1H), 7.75 (m, 1H), 7.50 (m, 2H), 7.36 (br s, 1H), 7.32 (d, 1H, J=4.7 Hz), 7.16 (m, 2H), 7.09 (d, 1H, J=8.4 Hz), 4.52 (s, 2H), 2.92 (s, 3H).
