実験手順

The title compound (50 mg, 95%) was synthesized as a green solid according to the method described for (E/Z)-3-((3-iodo-1H-indazol-6-yl)methylene)-5-methoxyindolin-2-one using 5-bromo-1H-pyrrolo[2,3-b]pyridin-2(3H)-one (21.3 mg, 0.1 mmol) and 1H-indazole-6-carbaldehyde (14.6 mg, 0.1 mmol). 1H NMR indicated 56:44 mixture of E/Z isomers. E isomer: 1H NMR (400 MHz, DMSO-d6) δ 13.38 (s, 1H, NH), 11.45 (s, 1H, NH), 8.38 (d, J=2.0 Hz, 1H), 8.25 (d, J=2.0 Hz, 1H), 8.19 (s, 1H), 8.01 (s, 1H), 7.93 (s, 1H), 7.90 (d, J=2.0 Hz, 1H), 7.45 (dd, J=8.4 Hz, 2.0 Hz, 1H); Z isomer: δ 13.46 (s, 1H, NH), 11.45 (s, 1H, NH), 8.94 (s, 1H), 8.21 (d, J=2.0 Hz, 1H), 8.19 (s, 1H), 8.15 (s, 1H), 7.99 (dd, J=8.8 Hz, 1.6 Hz, 1H), 7.94 (d, J=8.4 Hz, 1H), 7.85 (d, J=8.0 Hz, 1H); MS ESI 341.0 [M+H]+, calcd for [C15H9BrN4O+H]+ 341.1.
