N-methyl-2-pyrrolidone → [5-Bromo-7-(4-methanesulfonyl-phenyl)-pyrrolo[2,1-f][1,2,4]triazin-2-yl]-[4-(4-methyl-piperazin-1-yl)-phenyl]-amine

Reaction Steps

Into a 30 mL vial, 5-Bromo-2-methanesulfinyl-7-(4-methanesulfonyl-phenyl)-pyrrolo[2,1-f][1,2,4]triazine (0.14 g, 0.00034 mol), 4-(4-Methyl-piperazin-1-yl)-phenylamine (0.194 g, 0.00101 mol), and N-Methylpyrrolidinone (0.22 mL, 0.0023 mol) were added. The mixture was heated at 150° C. for 3 hours. The mixture was purified via ISCO column chromatography with DCM and MeOH as eluant (0 to 15% methanol). The collected fractions afforded [5-Bromo-7-(4-methanesulfonyl-phenyl)-pyrrolo[2,1-f][1,2,4]triazin-2-yl]-[4-(4-methyl-piperazin-1-yl)-phenyl]-amine as a yellow solid (80 mg, 44%). MP 265-266° C. LCMS (E/I+) 543.11 (M+H). NMR 1H (DSMO-d6)-9.49 (s, 1H), 8.93 (s, 1H), 8.45 (d, 2H, J=8.56 Hz), 8.03 (d, 2H, J=8.60 Hz), 7.55 (d, 2H, J=9.01 Hz), 7.35 (s, 1H), 6.96 (d, 2H, J=9.08 Hz), 3.39 (s, 3H), 3.10 (t, 4H, J=5.00 Hz), 2.47 (t, 4H, J=5.13 Hz), 2.23 (s, 3H).
