Procedure

In the manner described in Example 99, 5,5-bis(2-methoxyphenyl) -2,4-pentadienoic acid methyl ester (6.3 g) was saponified in a refluxing mixture of methanol (50 mL) and 1N NaOH (50 mL). After 45 minutes the crude acid was isolated in the normal manner and the crystallized from 2-propanol to yield 5.1 g of (E)-5,5-bis(2-methoxyphenyl)-2,4-pentadienoic acid, mp 96°-197° C.
