In the same manner as in Example 1, 2-(2,6-difluorobenzamido)pent-4-enoic acid methyl ester (17 mg) was reacted with 3-(N-(4-iodophenyl)-N-(pyrimidin-2-yl)amino)propanenitrile (24 mg) to obtain ((E)-5-[4-((2-cyano-ethyl)-pyrimidin-2-yl-amino)-phenyl]-2-(2,6-difluorobenzamido)-pent-4-enoic acid methyl ester (18 mg). Column chromatography (silica gel, eluent: hexane/ethyl acetate=2/1) was used for purification.
