Procedure

Oily sodium hydride (60%, 0.27 g) was added to a solution of morpholine (0.537 g) in N,N-dimethylformamide (20 ml), and the mixture was stirred at room temperature for 15 minutes. Then ethyl 2-chloromethyl-4-(3,4-dimethoxyphenyl)-6,7-dimethoxyquinoline-3-carboxylate (2.5 g) was added. The mixture was stirred at 100° C. for 2 hours, poured into water and extracted with ethyl acetate. The ethyl acetate layer was washed with water and dried over magnesium sulfate, and the solvent was evaporated. The residual crystals were separated by filtration, and then recrystallized from ethanol to give ethyl 4-(3,4-dimethoxyphenyl)-6,7-dimethoxy-2-morpholinomethylquinoline-3-carboxylate (1.9 g, 68%). Colorless prisms, mp. 146°-147° C.
