Procedure

In substantially the same manner as in Example 1, (E)-3-[2-(5-methyl-2-phenyl-4-oxazolylmethyl)benzofuran-5-yl]acrolein was allowed to react with 2,4-oxazolidinedione to give 5-[3-[2-(5-methyl-2-phenyl-4-oxazolylmethyl)benzofuran-5-yl]-2-propenylidene]-2,4-oxazolidinedione. The yield was 44%. Recrystallization from dichloromethane-methanol gave pale yellow needles, m-p.237°-239° C.
