Examples
specific Embodiment approach
[0253] Hereinafter, the present invention is preferably described in more detail with reference to Examples. However, these examples should not be construed as limiting the scope of the invention in any sense.
Synthetic example 1
[0254] (Intermediate Synthesis Example 1: Synthesis of Intermediate A)
[0255] 2,4-Dimethyldiphenylamine (10mol (mol)), benzyl bromide (10mol) and sodium hydride (10mol) were put into N,N-dimethylformamide, and the The mixture was heated to 80°C and stirred for 24 hours. Ethyl acetate was added to the solution, and the obtained mixture was washed twice to extract an organic layer. The extracted organic layer was distilled under reduced pressure and separated by column chromatography to obtain Intermediate A.

Synthetic example 2
[0258] (Intermediate Synthesis Example 2: Synthesis of Intermediate B)
[0259] 2,4-Dimethyldiphenylamine (10mol), (1-bromoethyl)benzene (10mol) and sodium hydride (10mol) were put into N,N-dimethylformamide, and the The mixture was heated to 80°C and stirred for 24 hours. Ethyl acetate was added thereto, and the obtained mixture was washed twice to extract an organic layer. The extracted organic layer was distilled under reduced pressure and separated by column chromatography to obtain Intermediate B.
