Procedure

In a similar manner as in Example 2, 3,4-bis(4-methoxyphenyl)-6-chloropyridazine (150 mg, 0.495 mmol) and 2,4-dichlorophenol were reacted as starting materials at 150° C. for 15 hours and post-treatment was then conducted, whereby the title compound was obtained as a colorless crystalline powder (195.5 mg, 93.9%). Melting point: 152.2-152.8° C. (ethyl acetate-hexane).
