Embodiment 1
[0039]Example 1: Synthesis of compound C-1
[0040]
[0041]Add L (7.1g, 10.6mmol), 3-methyldiphenylamine (4.7g, 25.4mol), Pd in a 250mL round bottom flask2(dba)3(0.08g, 0.4mmol), sodium tert-butoxide (3.4g, 0.035mol), tri-tert-butylphosphine (0.07g, 0.4mmol), toluene 60mL, and reflux and stir for 2 hours. After the reaction is completed, cool at room temperature. The reaction solution was extracted with dichloromethane and water. The organic layer was separated, dried with magnesium sulfate, and then concentrated under reduced pressure. The substance was separated and purified by column chromatography, and then recrystallized with dichloromethane and acetone to obtain compound C-1 (7.4 g, 85%). Mass spectrum m / z, theoretical value: 871.03; actually measured value: 870.32.
Embodiment 2
[0042]Example 2: Preparation of compound C-23
[0043]The synthesis method in Example 1 was used to obtain compound C-23. Mass spectrum m / z, theoretical value: 1039.28; measured value: 1038.43.
Embodiment 3
[0044]Example 3: Preparation of compound C-29
[0045]The synthesis method in Example 1 was used to obtain compound C-29. Mass spectrum m / z, theoretical value: 650.72; measured value: 650.21.
