Problems solved by technology

However, these methods are all reacted without a solvent, so workability is poor, and by-products such as chlorides of general formula (1) or (2) are generated, so they are not industrial methods

Embodiment

[0239] Hereinafter, the present invention will be described in more detail with examples and comparative examples, but the present invention is not limited to these examples. In the examples, unless otherwise specified, "part" means "mass part", and "%" means "mass %".

Synthetic example 1

[0241] (Synthesis of No.3 compound in Table 1)

[0242] (1) Under a nitrogen atmosphere, 3 parts of 4-ethylphenol and 1.3 parts of potassium hydroxide were dissolved in 60 parts of toluene, and heated to reflux. After stirring for 5 hours, it was cooled, and the precipitated solid was filtered. Then, under nitrogen flow, the precipitate, 2 parts of 1,5-dichloroanthraquinone and 0.6 part of copper powder were dissolved in 10 parts of DMF, and heated to reflux for 3 hours. The reaction solution was poured into an aqueous potassium hydroxide solution, and the precipitated solid was filtered, washed, and dried. Then, the inorganic matter was removed with toluene, and the obtained solid was recrystallized with 2-ethoxyethanol, filtered, washed, and dried to obtain 1.8 parts of 1,5-bis(4-ethylphenoxy)anthraquinone intermediate.

[0243] (2) A mixture of 0.5 parts of the intermediate obtained in (1) above, 6 parts of anhydrous aluminum chloride, 0.7 parts of hydroquinone and 4.8 pa...

Synthetic example 2

[0248] (Synthesis of No.125 compound in Table 2)

[0249] (1) Under a nitrogen atmosphere, 3.3 parts of thiophenol and 1.9 parts of potassium hydroxide were dissolved in 70 parts of toluene, and heated to reflux. After stirring for 4 hours, it was cooled and the precipitated solid was filtered. Then, under nitrogen flow, the precipitate, 3.5 parts of 1,5-dichloroanthraquinone and 0.6 part of copper powder were dissolved in 20 parts of DMF, and heated to reflux for 3 hours. The resulting reaction solution was poured into an aqueous potassium hydroxide solution, and the precipitated solid was filtered, washed, and dried. Then, inorganic substances were removed with toluene, and the obtained solid was recrystallized from 2-ethoxyethanol, filtered, washed, and dried to obtain 3.1 parts of intermediate 1,5-bis(phenylthio)anthraquinone.

[0250] (2) A mixture of 1 part of the intermediate obtained in (1) above, 12 parts of anhydrous aluminum chloride, 1.2 parts of hydroquinone and...
