Reaction Steps

As described in Example 99, (E,E)-5-(4-methoxyphenyl)-2,4-undecadienoic acid methyl ester (5.9 g) was saponified in a refluxing mixture of methanol (30 mL) and 2N NaOH (30 mL). After 3 hours the reaction was worked up in the usual way and the crude acid was crystallized from hexane to give 3.27 g of (E,E)-5-(4-methoxyphenyl)-2,4-undecadienoic acid, mp 8°-89.5° C.
