Participants

Reaction Steps

As described in Example 99, (2E,4Z)-5-(3-methoxyphenyl)-2,4-nonadienoic acid methyl ester (11 g) was saponified in a refluxing mixture of methanol (30 mL) and 2N NaOH (30 mL). After 2 hours the reaction was worked up in the usual way to yield 7.87 g of (2E,4Z)-5-(3-methoxyphenyl)-2,4-nonadienoic acid. A portion was crystallized from ether-hexane to give the analytical sample, mp 106.5°-107.5° C.
