실험 절차
As described in Example 99, (E)-3-(4-methoxyphenyl)-2-pentenal (7.1 g) was treated with (carbomethoxymethylene)triphenylphosphorane (14 g) in carbon tetrachloride (70 mL) and dichloromethane (15 mL) overnight at room temperature. The ester was isolated in the normal fashion to afford 8 g of (E,E)-5-(4-methoxyphenyl)-2,4-heptadienoic acid methyl ester as an oil.
