Reaction Steps

The title compound (61 mg, 84%) was synthesized as a yellow solid according to the method described for (E/Z)-3-((3-iodo-1H-indazol-6-yl)methylene)-5-methoxyindolin-2-one (oil temp 75° C., reflux 90 min) using oxindole (26.6 mg, 0.2 mmol) and (E)-3-(2-(pyridin-3-yl)vinyl)-1H-indazole-6-carbaldehyde (49.8 mg, 0.2 mmol). 1H NMR (400 MHz, DMSO-d6) δ 13.46 (s, 1H, NH), 10.64 (s, 1H, NH), 8.91 (s, 1H), 8.48 (d, J=4.4 Hz, 1H), 8.36 (d, J=8.4 Hz, 1H), 8.20 (d, J=8.4 Hz, 1H), 7.90 (s, 1H), 7.80 (s, 1H), 7.73 (d, J=16.8 Hz, 1H), 7.61 (d, J=7.2 Hz, 1H, partially overlapping with the peak at 7.60 ppm), 7.60 (d, J=17.2 Hz, 1H, partially overlapping with the peak at 7.61 ppm), 7.54 (d, J=8.4 Hz, 1H), 7.43 (dd, J=7.8 Hz, 4.8 Hz, 1H), 7.24 (t, J=7.8 Hz, 1H), 6.89 (d, J=7.6 Hz, 1H), 6.85 (t, J=7.8 Hz, 1H); MS ESI 365.1 [M+H]+, calcd for [C23H16N40+H]+ 365.1.
