[0509] Hereinafter, the specification will be described in detail with reference to Examples, Comparative Examples, and the like. However, the examples and comparative examples according to the present specification can be modified into various other forms, and the scope of the present specification should not be construed as being limited to the examples and comparative examples described below. Examples and comparative examples of this specification are provided to more fully describe this specification to those of ordinary skill in the art.
Synthetic example 1
[0511] Synthesis Example 1. Synthesis of Compound A-2-1
[0512]
[0513] In a three-necked flask, 1-bromo-3-chloro-5-methylbenzene (146mmol, 30g, 1eq) and bis(4-(tert-butyl)phenyl)amine (146mmol, 41.1g, 1eq) After dissolving in toluene (0.2M, 730ml), sodium tert-butoxide (219mmol, 21g, 1.5eq) and bis(tri-tert-butylphosphine)palladium(0) (1.46mmol, 0.75g, 0.01eq) were introduced into it , and the resultant was stirred at reflux for 1 h under an argon atmosphere. When the reaction was completed, the resultant was cooled to room temperature, and then distilled water was introduced thereinto, and the reaction solution was transferred to a separatory funnel and extracted. The extract was treated with MgSO 4 After drying and concentration, the sample was purified using silica gel column chromatography to obtain compound A-2-1 (49 g, yield 83%, MS[M+H]+=405).
Synthetic example 2
[0514] Synthesis Example 2. Synthesis of Compound A-2-2
[0515]
[0516] In a three-necked flask, 5-tert-butyl-[1,1'-biphenyl]-2-amine (66.6mmol, 15g, 1 equivalent) and 3-bromo-5,5,8,8-tetramethyl - After 5,6,7,8-tetrahydronaphtho[2,3-b]thiophene (66.6mmol, 21.5g, 1 eq) was dissolved in toluene (0.2M, 335ml), sodium tert-butoxide was introduced into it (99.9 mmol, 9.60 g, 1.5 equiv) and bis(tri-tert-butylphosphine)palladium(0) (0.666 mmol, 0.340 g, 0.01 equiv), and the resultant was stirred at reflux under an argon atmosphere for 12 hours. When the reaction was over, the resultant was cooled to room temperature, and then H was introduced into it 2 O, the reaction solution was transferred to a separatory funnel and extracted. The extract was treated with MgSO 4 After drying and concentration, the sample was purified using silica gel column chromatography to obtain compound A-2-2 (24.2 g, yield 78%, MS[M+H]+=468).
