Reaction Steps
As described in Example 99, (E)-3-(4-methoxyphenyl)-2-butenal (8 g) was treated with (carbomethoxymethylene)triphenylphosphorane (17 g) in carbon tetrachloride (70 mL) and dichloromethane (15 mL) overnight at room temperature. The ester was isolated in the normal fashion and crystallized from hexane to afford 7.2 g of (E,E)-5-(4-methoxyphenyl)-2,4hexadienoic acid methyl ester, mp 84°-86° C.
