Participants

Reaction Steps

7-(3,6-Dimethoxy-pyridazin-4-yl)-pyrrolo[2,1-f][1,2,4]triazin-2-ol (70 mg, 0.2 mmol), N-Phenylbis(trifluoromethanesulphonimide) (95.1 mg, 0.266 mmol), N,N-Diisopropylethylamine (0.126 mL, 0.726 mmol), and N,N-Dimethylformamide (2 mL, 30 mmol) and stir at room temperature for half an hour. Add 2-[4-(4-Amino-phenyl)-piperidin-1-yl]-acetamide (90.3 mg, 0.387 mmol) and stir at 60° C. overnight. An LCMS showed product. The reaction was concentrated, DMSO added, filtered and placed onto the Gilson for purification. The most pure fractions were collected, free based with saturated sodium bicarbonate, extracted with DCM, filtered and concentrated to give 2-(4-{4-[7-(3,6-Dimethoxy-pyridazin-4-yl)-pyrrolo[2,1-f][1,2,4]triazin-2-ylamino]-phenyl}-piperidin-1-yl)-acetamide as a yellow solid (15 mg, 10%). MP 249-251° C. LCMS (E/I+) 489 (M+H).
