[0043] According to the preparation method provided by the present invention, those skilled in the art can use known common means to realize, such as further selecting a suitable catalyst and solvent, determining a suitable reaction temperature, time, etc., which are not particularly limited in the present invention. The solvents, catalysts, bases and other raw materials used in the preparation process can be synthesized through open commercial channels or methods known in the art.
[0044] Using the preparation method provided by the invention, a series of compounds represented by general formula (I) were prepared.
[0045] Synthesis of Intermediates M1~M8
[0046] Synthesis of intermediate M1
[0047]
[0048] The synthetic route is as follows:
[0049]
[0050] The synthesis process comprises the following specific steps:
[0051] (1) Add 2-bromo-6-iodobiphenyl (35.8g, 0.10mol) and anhydrous tetrahydrofuran into a dry 1L three-necked flask under nitrogen protection...
Embodiment 1
[0084] The synthesis of embodiment 1 compound 1-2
[0085]
[0086] The synthetic route is as follows:
[0087]
[0088] The synthesis process includes steps: take a 1L three-neck flask, equip it with magnetic stirring, add potassium tert-butoxide (11.2g, 0.1mol), bis(4-isopropylphenyl)aniline (25.3g, 0.1mol) and 400ml of toluene; after nitrogen replacement again, (0.4g, 2mmol) tri-tert-butylphosphine and (0.2g, 1mmol) palladium acetate were added in sequence. After the addition was complete, the temperature was raised to 85°C. A solution consisting of M4 (64.7 g, 0.1 mol) and 100 ml of toluene was started to be added dropwise, and the temperature was controlled at 80-120° C. to react for 4 hours, and the reaction was completed. Adjust to neutrality, separate the organic phase, extract, dry, perform column chromatography, and spin dry the solvent to obtain 61.52 g of light yellow solid with a yield of about 75%.

[0090] The synthesis of embodiment 2 compound I-16
[0091]
[0092] The synthetic route is as follows:
[0093]
[0094] Replace M4 with M1, bis-biphenylamine replaces two (4-isopropylphenyl) aniline, select suitable material ratio, other raw materials and steps are all identical with embodiment 1, obtain 72.84g light yellow solid, yield approx. 82%.
[0095] Product MS (m / e): 888.28; Elemental analysis (C 63 h 40 N 2 o 2 S): theoretical value C: 85.11%, H: 4.53%, N: 3.15%; measured value C: 85.16%, H: 4.58%, N: 3.13%.
