Procedure

(E,E)-5-[4-[2-(5-methyl- 2-phenyl-4-oxazolyl )ethyl]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)-5-[4-[2-(5-methyl-2-phenyl4-oxazolyl)ethyl]phenyl]-2,4-pentadien-1-al, which was then recrystallized from ethyl acetate to yield yellow rods having a melting point of 107°-108° C.
