Reaction Steps

4-(6-(3-(Dimethylamino)propoxy)-5-methylpyrrolo[2,1-f][1,2,4]triazin-4-yloxy)-3-fluorobenzenamine (12 mg, 0.03 mmol) was converted to the title compound (2.5 mg, 13%) in a manner similar to the preparation of Compound E of Example 31, except that 2-(4-fluorophenyl)-acetyl isocyanate (0.10 mL, 0.04 mmol, Compound C of Example 4) was used instead of benzenesulfonyl isocyanate. 1H NMR (CD3OD) δ 10.77 (s, 1H), 7.80 (s, 1H), 7.69 (s, 1H), 7.40-7.23 (m, 5H), 7.11-7.02 (m, 3H), 4.15-4.12 (m, 2H), 3.71 (s, 2H), 3.41-3.36 (m, 2H), 2.97 (s, 6H), 2.44 (s, 3H), 2.31-2.22 (m, 2H); HRMS(ESI), 539.2218 (M+H)+ calc, 539.2218 (M+H)+ found.
