Reaction Steps

As described in Example 99, (2E,4Z)-5-cyclohexyl-5-(4-methoxyphenyl)-2,4-pentadienoic acid methyl ester (5.2 g) was saponified in a refluxing mixture of methanol (20 mL) and 2N NaOH (20 mL). After 2.5 hours the crude product was isolated in the usual way crystallized from 2-propanol-hexane to give 3.5 g of (2E,4Z)-5-cyclohexyl-5-(4-methoxyphenyl]-2,4-pentadienoic acid, mp 185°-186° C.
