Reaction Steps

Into a 30 mL vial, 2-Methanesulfinyl-7-(4-methanesulfonyl-phenyl)-pyrrolo[2,1-f][1,2,4]triazine (80 mg, 0.0002 mol), 4-(4-Methyl-piperazin-1-yl)-phenylamine (0.100 g, 0.000525 mol) and N-Methylpyrrolidinone (0.25 mL, 0.0026 mol) were added. The reaction mixture was heated at 150° C. for 90 minutes. The reaction was cool to room temperature. Methanol (15 mL) was added. The solid was filtered and washed with hot MeOH (10 mL) to afford [7-(4-Methanesulfonyl-phenyl)-pyrrolo[2,1-f][1,2,4]triazin-2-yl]-[4-(4-methyl-piperazin-1-yl)-phenyl]-amine as a light brown solid. MP 234-238° C. LCMS (E/I+) 373.18 (M+H). NMR 1H (DSMO-d6)-9.31 (s, 1H), 9.00 (s, 1H), 8.48 (d, 2H, J=8.48 Hz), 8.02 (d, 2H, J=8.16 Hz), 7.57 (d, 2H, J=8.79 Hz), 7.33 (d, 1H, J=4.77 Hz), 6.95 (d, 1H, J=4.76 Hz), 6.95-7.04 (m, 3H), 3.28 (s, 3H), 3.09 (bs, 4H), 2.40-2.56 (m, 4H), 2.22 (s, 3H).
