Reaction Steps
In a similar fashion, (Z)-5,5-bis(3-methoxyphenyl)-2,4-pentadienoic acid ethyl ester (2.2 g) in methanol (15 mL) was hydrolyzed using 2N sodium hydroxide solution (5 mL). The usual work up furnished 2.0 g of (Z)-5,5-bis(3-methoxyphenyl)-2,4-pentadienoic acid. Crystallization of a portion from ether furnished the analytically pure acid, mp 178°-180° C.
