Reaction Steps

The title compound (34 mg, 53%) was synthesized as a orange red solid according to the method described for Example A67 (oil temp 75° C., reflux 2 h) using 5-methoxylindolin-2-one (29 mg, 0.18 mmol) and 3-(pyridin-3-ylethynyl)-1H-indazole-6-carbaldehyde (40 mg, 0.163 mmol), followed by additional 90 min with additional 5-methoxylindolin-2-one (5.8 mg, 0.036 mmol). 1H NMR (400 MHz, DMSO-d6) δ 13.80 (s, br, 1H, NH), 10.46 (s, 1H, NH), 8.90 (s, 1H), 8.63 (d, J=4.4 Hz, 1H), 8.12 (dt, J=8.0 Hz, 1H), 8.04 (d, J=8.4 Hz, 1H), 7.98 (s, 1H), 7.79 (s, 1H), 7.58 (d, J=8.4 Hz, 1H), 7.52 (dd, J=8.0 Hz, J=4.8 Hz, 1H), 7.13 (d, J=1.6 Hz, 1H), 6.86 (dd, J=8.0 Hz, J=2.4 Hz, 1H), 6.80 (d, J=8.4 Hz, 1H), 3.59 (s, 3H); MS ESI 393.2 [M+H]+, calcd for [C24H16N4O2+H]+ 393.1.
