Participants

Reaction Steps

According to the procedure for the synthesis of 3-((3-(6-(4-methylpiperazin-1-yl)pyridin-3-yl)-1H-indazol-6-yl)methylene)indolin-2-one, except substituting 5-methoxyoxindole (28 mg, 0.087 mol), the title compound was prepared as a yellow solid (14.4 mg, 35%). A mixture of (E)- and (Z)-isomers (83:17 by NMR) was obtained. 1H NMR (400 MHz, CD3OD) 8.74 (d, J=2.3 Hz, 1H), 8.14 (dd, J=8.8, 2.3 Hz, 1H), 8.07 (d, J=8.5 Hz, 1H), 7.87 (d, J=10.0 Hz, 2H), 7.49 (d, J=8.3 Hz, 1H), 7.26 (s, 1H), 7.01 (d, J=8.8, 1H), 6.83 (s, 2H), 3.75-3.69 (br. m, 4H), 3.62 (s, 3H), 2.82-2.76 (br. m, 4H), 2.51 (s, 3H); MS ESI 467.2 [M+H]+, calcd for [C27H26N6O2+H]+ 467.21.
