実験手順
In the same manner as in Example 1, 2-(2,6-dichlorobenzamido)pent-4-enoic acid methyl ester (50.0 mg) was reacted with 2-(4-iodophenoxy)-5-ethylpyrimidine (54.1 mg) to obtain (E)-2-(2,6-dichlorobenzamido)-5-[4-(5-ethylpyrimidin-2-yloxy)phenyl]pent-4-enoic acid methyl ester (62.2 mg). Column chromatography (chloroform) and thin layer chromatography (cyclohexane/ethyl acetate=1/2) were used for purification.
