Procedure
In the same manner as in Example 1, 2-(2,6-dichlorobenzamido)pent-4-enoic acid methyl ester (59.3 mg) was reacted with N-benzyl-N-(4-iodophenyl)pyrimidin-2-amine (67.0 mg) to obtain (E)-5-[4-(benzyl-pyrimidin-2-yl-amino)-phenyl]-2-(2,6-dichlorobenzamido)-pent-4-enoic acid methyl ester (58.7 mg). Column chromatography (silica gel, eluent: chloroform/cyclohexane=2/1 chloroform) and thin layer chromatography (silica gel, mobile phase: cyclohexane/ethyl acetate=2/1) were used for purification.
