In the same manner as in Example 1, 2-(2,6-dichlorobenzamido)pent-4-enoic acid methyl ester (214 mg) was reacted with N-(4-iodophenyl)-N-ethylpyrimidin-2-amine (254 mg) to obtain (E)-2-(2,6-dichlorobenzamido)-5-[4-(ethyl-pyrimidin-2-ylamino)phenyl]pent-4-enoic acid methyl ester (258 mg). Column chromatography (silica gel, eluent: hexane/ethyl acetate=4/1→hexane/ethyl acetate=2/1 hexane/ethyl acetate=1/2) was used for purification.
