Embodiment 1
[0047] Present embodiment prepares formula according to following circuit (M 0 ) intermediate of the structure shown:
[0048]
[0049] This embodiment is synthesized according to the following steps with reference to the method shown in Chinese patent CN103570620A:
[0050] (1) Synthesis of P1
[0051] In a 500ml three-necked flask, add 1-bromo-2-methylnaphthalene, concentrated sulfuric acid, and 1,2-dichloroethane to mix well, control the temperature below 0°C, slowly add nitric acid dropwise while stirring, and keep 0- Stir at 5°C for 2 hours, slowly pour into ice water, separate the layers and wash the organic layer with water, dry and separate by silica gel column chromatography, and elute with ethyl acetate-petroleum ether eluent with a volume ratio of 1:2 , to obtain light yellow product P1;
[0052] (2) Synthesis of P2
[0053] In a 500 ml three-necked flask, add P1, carbon tetrachloride, N-bromosuccinimide and a small amount of benzoyl peroxide prepared in step...
Embodiment 2
[0062] This embodiment prepares the compound shown in formula M1 according to the following synthetic route:
[0063]
[0064] Under nitrogen protection, DMPU (1,3-dimethylpropylene urea) was added to the three-necked flask, and the intermediate M prepared in Example 1 0 , 7-iodo-N,N-p-toluenetriphenylene-2-amine, potassium carbonate, cuprous iodide, and 18-crown-6, mix well, heat the oil bath to reflux for 2 hours, cool down and pour the reaction solution into distilled water , extracted with dichloromethane, dried over magnesium sulfate, concentrated to dryness, and crystallized with a mixed solvent of ethanol and toluene to obtain a yellowish solid M1.
Embodiment 3
[0066] The preparation method of compound M2 in this example is the same as in Example 2, the only difference is that the raw material 7-iodo-N,N-p-toluenetriphenylene-2-amine is replaced by 6,6,9,12,12-penta Methyl-biphenyl-6,12-[1,2-b]N,N-p-tolyltriphenylene-2-amine, other raw materials and preparation methods are the same.
