A mixture of 7-chloro-2-(5-methoxycarbonyl-3-hydroxybenzofuran-2-yl)quinoline (1.0 g), potassium carbonate (0.39 g), and methyl iodide (0.40 g) in a mixture of tetrahydrofuran (20 ml) and N,N-dimethylformamide (8 ml) was stirred under reflux. After being cooled, the appeared precipitates were collected by filtration and washed with acetone to give 7-chloro-2-(5-methoxycarbonyl-3-methoxybenzofuran-2-yl)quinoline (0.51 g).
