According to the method described for Reference Example 35, (E)-3-[4-[5-methyl-2-(2-naphthyl)-4-oxazolylmethoxy]phenyl]-2-propen-1-al was allowed to react with diethyl cyanomethylphosphonate to give (E,E)-5-[4-[5-methyl-2-(2-naphthyl)-4-oxazolylmethoxy]phenyl]-2,4-pentadienenitrile. Recrystallization from ethyl acetate--ether gave colorless prisms, m.p.159°-160° C.
