Procedure
In a similar manner as in Example 2, 3,4-bis(4-methoxyphenyl)-6-chloropyridazine (250 mg, 0.766 mmol) and 3,5-difluorophenol were reacted as starting materials at 150° C. for 6 hours and post-treatment was then conducted, whereby the title compound was obtained as colorless needles (315.0 mg, 98.0%). Melting point: 135.1-137.5° C. (ethyl acetate-diethyl ether-hexane).
