Embodiment 1
[0082] Example 1: 3-(1H-benzimidazole-2-methylene)-2-indolinone (L001) and its preparation
[0083] Suspend 0.05g (0.25mmol) of 2-indolinone and 0.04g (0.27mmol) of 1H-benzimidazole-2-carbaldehyde in 2ml of absolute ethanol, add 2 drops of piperidine, and heat to reflux in an oil bath for 30min , a large amount of orange-yellow solid was precipitated, filtered, and washed with absolute ethanol to obtain 0.05 g of light yellow solid, with a yield of 62.5%.
[0084] The analysis result of its nuclear magnetic resonance spectrum is: 1 H-NMR (DMSO-d6) δ (ppm): δ 13.99 (s, 1H, NH), 11.30 (s, 1H, NH), 7.95 (s, 1H, CH), 7.93 (d, 1H, J= 7.6Hz, Ar-H), 7.79(d, 1H, J=8.0Hz, Ar-H), 7.75(d, 1H, J=8.0Hz, Ar-H), 7.29-7.37(m, 3H, Ar- H), 7.08 (t, 1H, Ar-H), 6.95 (d, 1H, J = 7.6 Hz, Ar-H). ESI-MS m / z: 262 [M+H]+ (100).
