Vorschrift

In substantially the same manner as in Reference Example 7, ethyl (E,E)-5-(4-isopropoxyphenyl)-2,4-pentadienate was reduced with diisobutylaluminium hydride to give (E,E)-5-(4-isopropoxyphenyl)-2,4-pentadien-1-ol. Recrystallization from isopropyl ether gave colorless needles. Melting point 91-92° C.
