In substantially the same manner as in Reference Example 35, (E,E)-5-[3-methoxy-4-(5-methyl-2-phenyl-4-oxazolylmethoxy)phenyl]-2,4-pentadien-1-ol was subjected to oxidation with activated manganese dioxide to yield (E,E)-5-[3-methoxy-4-(5-methyl-2-phenyl-4-oxazolylmethoxy)phenyl]-2,4-pentadien-1-al, which was recrystallized from ethyl acetate to give colorless needles, m.p.133-134° C.
