Procedure

In a nitrogen atmosphere, 1 g (9 mmole) of maminophenol was dissolved in 20 ml of DMI, and 2 g (15 mmole) of potassium carbonate was added, followed by stirring for 30 minutes. Then, 1 g (2 mmole) of 1,3-bis(3-(3-fluorophenoxy)phenoxy)benzene was added, and the mixture was stirred for 14 hours under heating at 210° C. The progress of the reaction was confirmed by HPLC. When the intermediate product, 3-(3-(3-aminophenoxy)phenoxy)phenyl-3-(3-(3-fluorophenoxy)phenoxy)phenyl ether almost disappeared, the reaction was terminated. Then, liquid separation was carried out in the same manner as in Example 2 to obtain an organic phase, and the solvent was distilled off under reduced pressure. The residue was purified by column chromatography to obtain 1.1 g (1.6 mmole, yield: 86%, purity (HPLC): 98%) of 1,3-bis(3-(3-(3-aminophenoxy)phenoxy)phenoxy)benzene as a yellow oily product. The structure and the properties of the compound are as follows.
