Procedure
[2-(2-Furyl)-5-methyl-4-oxazolylmethyl]triphenylphosphonium chloride and methyl 4-formylbenzoate were reacted in the same manner as in Reference Example 10 to yield methyl (E)-4-[2-[2-(2-furyl)-5-methyl-4-oxazolyl]vinyl]benzoate, which was then recrystallized from ethyl acetate to yield colorless prisms having a melting point of 142°-143° C.
