Versuchsvorschrift
Ethyl (E,E)-5-[4-[2-(5-methyl-2-phenyl-4-oxazolyl)ethyl]phenyl]-2,4pentadienoate was reduced with diisobutylaluminum hydride in the same manner as in Reference Example 22 to yield (E,E)-5-[4-[2-(5-methyl-2-phenyl4-oxazolyl)ethyl]phenyl]-2,4-pentadien-1-ol, which was then recrystallized from ethyl acetate-hexane to yield colorless prisms having a melting point of 117°-118° C.
