Procedure

5-(4'-phenylphenyl)-4-pentyn-1-ol was prepared from 4-pentyn-1-ol and 4'-bromobiphenyl as in Example 15, and converted into 5-(4'-phenylphenyl)-4-pentyn-1-al by the method of Example 9. N-isobutyl 7-(4'-phenylphenyl)-(2E)-hepten-6-ynamide was then prepared from 5-(4'-phenylphenyl)-4-pentyn-1-pentyn-1-al and N-isobutylacetamidotriphenylphosphonium chloride as in Example 9 and semi-hydrogenated as in Example 9 to give N-isobutyl 7-(4'-phenylphenyl)-(2E,6Z)-heptadienamide.
