According to the method described for Reference Example 34, (E)-3-[3-(5-methyl-2-phenyl-4-oxazolylmethoxy)phenyl]-2-propen-1-ol was subjected to oxidation with activated manganese dioxide to give (E)-3-[3-(5-methyl-2-phenyl-4-oxazolylmethoxy)phenyl]-2-propen-1-al. Recrystallization from ethyl acetate--hexane gave colorless prisms, m.p.103°-104° C.
