Versuchsvorschrift

In a similar manner as in Example 2, 3,4-bis(4-methoxyphenyl)-6-chloropyridazine (200 mg, 0.613 mmol) and 2,5-difluorophenol were reacted as starting materials at 150° C. for 24 hours and post-treatment was then conducted, whereby the title compound was obtained as a colorless crystalline powder (235.5 mg, 91.5%). Melting point: 174.4-175.2° C. (chloroform-hexane).
