Embodiment 1
[0057] [Example 1] Synthesis of Compound A1
[0058]
[0059] Synthesis of intermediate a1-1
[0060] Take 2-(3,5-dichlorophenyl)pyridine (9.5g, 42.4mmol) into a three-necked flask, add THF 100mL, protect with nitrogen, stir at -78°C for 30 minutes, then add n-butyllithium (2.5M) 21 mL, reacted for 1 hour, then added 14 g of triisopropyl borate, reacted at low temperature for 1 hour, and gradually returned to room temperature. In the post-treatment process, 2M hydrochloric acid was added to the system to make the pH of the solution 4-5, and the liquid separation was allowed to stand. The aqueous layer was extracted with ethyl acetate, the organic layers were combined, and spin-dried to obtain intermediate a1-1 (8.2g, yield 80%).

Embodiment 2
[0068] [Example 2] Synthesis of Compound A13
[0069]
[0070] The 2-bromo-9,9-dimethylfluorene in Example 1 was replaced by equimolar 2-bromo-9,9-spirobifluorene, and the other steps were the same as the synthesis of Example 1 to obtain the target product compound A13. Mass Spectrum m / z: 1092.26 (calculated: 1092.29). Theoretical element content (%)C 81 h 49 N 5 : C, 89.07; H, 4.52; N, 6.41 Measured element content (%): C, 89.08; H, 4.51; N, 6.41. The above results confirmed that the obtained product was the target product.
Embodiment 3
[0071] [Example 3] Synthesis of Compound A27
[0072]
[0073] In Example 1, the 2-bromo-9,9-dimethylfluorene was replaced by equimolar 2-bromo-9,9-diphenylfluorene, and 2-(3,5-dichlorobenzene)pyridine was replaced by Equimolar 3-(3,5-dichlorophenyl)pyridine, and other steps were the same as in Example 1 to obtain the target compound A27. Mass Spectrum m / z: 1096.26 (calculated: 1096.32). Theoretical element content (%)C 81 h 53 N 5: C, 88.74; H, 4.87; N, 6.39 Measured element content (%): C, 88.76; H, 4.86; N, 6.38. The above results confirmed that the obtained product was the target product.
