반응 단계
Oily sodium hydride (60%, 0.323 g) was added to a solution of 2-ethylimidazole (0.776 g) in N,N-dimethylformamide (30 ml), followed by stirring at room temperature for 15 minutes. Then 2-chloromethyl-6,7-dimethoxy-4-(3,4-dimethoxyphenyl)quinoline-3-carboxylic acid ethyl ester (3.0 g) was added. After stirring at 80° C. for 1 hour, the reaction mixture was poured over water, and the separating crystal was collected by filtration, which was then recrystallized from ethanol to yield 6,7-dimethoxy-4-(3,4-dimethoxyphenyl)-2-(2-ethylimidazol-1-ylmethyl)quinoline-3-carboxylic acid ethyl ester (2.5 g, 74%) as a colorless prismatic crystal having a melting point of 163° to 164° C.
