반응 단계
In substantially the same manner as in Example 1, (E,E)-5-[4-[2-(5-methyl-2-phenyl-4-oxazolyl)ethoxy]phenyl]-2,4-pentadien-1-al was allowed to react with 2,4-oxazolidinedione to give 5-[5-[4-[2-(5-methyl-2-phenyl-4-oxazolyl)ethoxy]phenyl]-2,4-pentadienylidene]-2,4-oxazolidinedione. The yield was 31%. Recrystallization from dichloromethane-methanol gave yellow needles, m.p.209°-211° C.
