Vorschrift

In the same manner as in Example 1, 2-(2,6-dichlorobenzamido)pent-4-enoic acid methyl ester (60.4 mg) was reacted with tetrahydro-4-(4-iodophenyl)-4-ethoxy-2H-pyran (66.4 mg) to obtain (E)-2-(2,6-dichlorobenzamido)-5-[4-(4-ethoxytetrahydropyran-4-yl)-phenyl]pent-4-enoic acid methyl ester (68.9 mg). Column chromatography (silica gel, eluent: cyclohexane/chloroform=2/1→cyclohexane/ethyl acetate=4/1) was used for purification.
