Procedure

(E,E,E)-5-[4-[2-[2-(2-Furyl)-5-methyl-4-oxazolyl]vinyl]phenyl]-2,4-pentadien-1-ol was oxidized with activated manganese dioxide in the same manner as in Reference Example 25 to yield (E,E,E)-5-[4-[2-[2-(2-furyl)-5- methyl-4-oxazolyl]vinyl]phenyl]-2,4-pentadien-1-al, which was then recrystallized from ethyl acetate to yield light brown prisms having a melting point of 179°-180° C.
