Reaction Steps

To a solution of 3-fluoro-4-(5-methyl-6-(2-(4-methylpiperazin-1-yl)ethoxy)pyrrolo[2,1-f][1,2,4]triazin-4-yloxy)benzenamine 30 mg, 0.075 mmol) and 1-(4-fluorophenyl)-2-oxo-1,2-dihydropyridine-3-carboxylic acid in DMF (1.0 mL) at room temperature were added HATU (57 mg, 0.15 mmol, Perseptive Biosystem), and DIEA (0.05 mL, 0.3 mmol, Aldrich). The reaction mixture was stirred at rt for 1 h, and was then quenched by the addition of 2 mL of methanol. The reaction mixture was purified by preparative HPLC. The desired fractions were combined, concentrated in vacuo, and neutralized to pH 8 with aq. K2HPO4. The title compound (30 mg, 64%) was obtained as a white solid which was collected by filtration and dried under vaccum. 1H NMR (DMSO-d6) δ 12.09 (br s, 1H), 8.58 (dd, 1H, J=7.15, 2.20 Hz, 1H), 8.12 (dd, 1H, J=6.60, 1.65 Hz), 7.98 (s, 1H), 7.95 (d, 2H, J=3.85 Hz), 7.62-7.59 (m, 2H), 7.45-7.40 (m, 4H), 6.72 (t, 1H, J=9.90 Hz), 4.13 (t, 2H, J=5.5 Hz), 2.71 (d, 2H, J=5.5 Hz), 2.60-2.25 (m, 8H), 2.35 (s, 3H), 2.16 (s, 3H); MS(ESI30) m/z 616.40 (M+H)+.
