Participants

Reaction Steps

The title compound (59 mg, 81%) was synthesized as an orange solid according to the method described for Example A67 (oil temp 75° C., reflux 90 min) using 1H-pyrrolo[2,3-b]pyridin-2(3H)-one (26.8 mg, 0.2 mmol) and (E)-3-(2-(pyridin-3-yl)vinyl)-1H-indazole-6-carbaldehyde (49.8 mg, 0.2 mmol). 1H NMR indicated 5:2 mixture of Z/E isomers. 1H NMR (400 MHz, DMSO-d6) δ 13.60 (s, 1H, NH), 11.30 (s, 1H, NH), 8.95 (s, 1H), 8.91 (d, 1H), 8.47 (d, J=4.4 Hz, 1H), 8.31 (d, J=8.4 Hz, 1H), 8.19 (d, J=7.2 Hz, 1H), 8.13-8.07 (m, 4H), 7.72 (d, J=16.8 Hz, 1H), 7.59 (d, J=17.2 Hz, 1H), 7.42 (dd, J=8.0 Hz, 4.4 Hz, 1H), 7.50 (dd, J=7.2 Hz, 5.6 Hz, 1H); MS ESI 444.3 [M+H]+, calcd for [C22H15N5O+H]+ 366.1.
