Procedure
(E)-3-[4-[2-(5-Methyl-2-phenyl-4-oxazolyl)ethyl]phenyl]-2-propenol was oxidized with activated manganese dioxide in the same manner as in Reference Example 25 to yield 4-[2-(5-methyl-2-phenyl-4-oxazolyl)ethyl]cinnamaldehyde, which was then recrystallized from ethyl acetate-hexane to yield colorless prisms having a melting point of 99°-100° C.
