In the same manner as in Example 1, 2-(2,6-dichlorobenzamido)pent-4-enoic acid methyl ester (89 mg) was reacted with N-(4-iodophenyl)-N-(2-methoxyethyl)pyrimidin-2-amine (116 mg) to obtain (E)-2-(2,6-dichlorobenzamido)-5-[4-((2-methoxyethyl)-pyrimidin-2-ylamino)phenyl]pent-4-enoic acid methyl ester (120 mg). Column chromatography (silica gel, eluent: cyclohexane/chloroform=2/1→cyclohexane/chloroform=1/1→cyclohexane/chloroform=1/2) was used for purification.
