Procedure
By the procedure of Example 1, 2-chloro-4-methoxy-5,6-dimethyl-benzyl-triphenylphosphonium chloride is reacted with 7-formyl-3-methyl-octa-2,4,6-trien-1-oic acid ethyl ester to obtain 9-(2-chloro-4-methoxy-5,6-dimethyl-phenyl)-3,7-dimethyl-nona-2,4,6,8-tetraen-1-oic acid ethyl ester, a yellow-red oil.
