Procedimiento

(E)-4-[2-(5-Methyl-2-phenyl-4-oxazolyl)vinyl]cinnamaldehyde and 2,4oxazolidinedione were reacted in the same manner as in Reference Example 28 to yield (E,E)-5-[4-[2-(5-methyl-2-phenyl-4-oxazolyl)vinyl]cinnamylidene]2,4-oxazolidinedione, which was then recrystallized from chloroform-methanol to yield yellow needles having a melting point of 274°-275° C.
