反応手順
In the same manner as in Example 1, 2-(2,6-dichlorobenzamido)pent-4-enoic acid methyl ester (2.11 g) was reacted with tetrahydro-4-(4-iodophenyl)-4-methoxy-2H-pyran (2.22 g) in the presence of potassium carbonate (1.45 g), palladium acetate (81.7 mg) and tris(2-methylphenyl)phosphine (106.2 mg) to obtain (E)-2-(2,6-dichlorobenzamido)-5-[4-(4-methoxytetrahydropyran-4-yl)-phenyl]pent-4-enoic acid methyl ester (2.74 g). Column chromatography (silica gel, eluent: cyclohexane/chloroform=2/1→cyclohexane/ethyl acetate=10/1→cyclohexane/ethyl acetate=4/1) was used for purification.
