Participants

Reaction Steps

To a solution of DCM (5 mL) was added N-{4-[4-amino-6-(hydroxymethyl)pyrrolo[2,1-f][1,2,4]triazin-5-yl]phenyl}-N′-(4-methylpyridin-2-yl)urea (Example 262) (40 mg, 0.10 mmol) followed by 2M thionyl chloride in DCM (0.51 mL, 1.03 mmol). The solution was stirred at rt for 1 h and was then evaporated in vacuo. THF (5 mL) and MeOH (5 mL) were added to the crude reaction followed by triethylamine (43 μL, 0.31 mmol). The solution was heated to 50° C. for 3 d and then evaporated in vacuo and purified by MPLC (Isco) 0-5% MeOH/DCM. The resulting purified fractions were combined and evaporated producing 25 mg of the title compound (0.061 mmol, yield 60%). 1H-NMR (DMSO-d6) δ 10.86 (s, 1H), 9.46 (s, 1H), 8.14 to 8.13 (d, J=6.3 Hz, 1H), 7.84 (s, 1H), 7.75 (s, 1H), 7.65 to 7.63 (d, J=8.7 Hz, 2H), 7.36 to 7.34 (d, J=8.6 Hz, 2H), 7.27 (s, 1H), 6.87 to 6.86 (d, J=5.0 Hz, 1H), 4.27 (s, 2H), 3.20 (s, 3H), 2.30 (s, 3H); MS [M+H]+=404.0; LCMS RT=1.99 min.
