Procedure
As described in Example 99, (E,E)-5-(4-methoxyphenyl)-2,4-heptadienoic acid methyl ester (8 g) was saponified in a refluxing mixture of methanol (30 mL) and 2N NaOH (30 mL). After 2.5 hours the reaction was worked up in the usual way and the acid crystallized from 2-propanol-hexane to give 5.4 g of (E,E)-5-(4-methoxyphenyl)-2,4-heptadienoic acid, mp 135.5°-137° C.
