Procedure

By the procedure of Example 6: 2,4,6-triisopropyl-benzyl-triphenylphosphonium bromide is condensed with 7-formyl-3-methyl-octa-2,4,6-trien-1-oic acid butyl ester to form 9-(2,4,6-triisopropyl-phenyl)-3,7-dimethyl-nona-2,4,6,8-tetraen-1-oic acid butyl ester (oil); which is hydrolyzed by the procedure of Example 7 to form: 9-(2,4,6-triisopropyl-phenyl)-3,7-dimethyl-nona-2,4,6,8-tetraen-1-oic acid m.p.: 221° C.
