実験手順

A mixture of ethyl 2-iodomethyl-6,7-dimethoxy-4-(3,4-dimethoxyphenyl)quinoline-3-carboxylate (9.0 g), 2-hydroxy-1-methylimidazole (1.8 g), silver (I) carbonate (Ag2CO3)(5.1 g) and benzene (100 ml) was stirred at 50° C. for 18 hours. The insoluble solid was filtered off. The filtrate was washed with water and dried over magnesium sulfate, and the solvent was evaporated. The residual oil was subjected to column chromatography on silica gel. The fractions eluted with chloroform/ethyl acetate (5/1, v/v) gave ethyl 6,7-dimethoxy-4-(3,4-dimethoxyphenyl)-2-[(1-methyl-2-imidazolyl)oxymethyl]quinoline-3-carboxylate (0.8 g, 9%) which was then recrystallized from ethyl acetate-hexane.
