Participants

Reaction Steps

As described in Example 99, (E,E)-5-(4-methoxyphenyl)-2,4-decadienoic acid methyl ester (6.1 g) was saponified in a refluxing mixture of methanol (25 mL) and 2N NaOH (25 mL). After 45 minutes the reaction was worked up in the usual way and the crude acid crystallized from 2-propanol to give 4.7 g of (E,E)-5-(4-methoxyphenyl)-2,4-decadienoic acid, mp 126°-127.5° C.
