Procedure

In the same manner as in Example 1, 2-(2,6-dichlorobenzamido)pent-4-enoic acid methyl ester (80 mg) was reacted with N-(4-iodophenyl)-4,6-dimethoxy-N-methylpyrimidin-2-amine (118 mg) to obtain (E)-2-(2,6-dichlorobenzamido)-5-[4-((4,6-dimethoxy-pyrimidin-2-yl)-methyl-amino)phenyl]pent-4-enoic acid methyl ester (92 mg). Column chromatography (silica gel, eluent: hexane/ethyl acetate=2/1) was used for purification.
