Reaction Steps

To a stirred mixture of 8-benzyloxy-4-carboxy-2-methylquinoline (700 mg), potassium carbonate (659 mg) and N,N-dimethylformamide (0.3 ml) was dropwise added ethyl iodide (409 mg) under ice-cooling and the mixture was stirred for 30 minutes at the same temperature and for 1 hour at ambient temperature. To the mixture was added water and extracted with ethyl acetate. The organic layer was washed with water and brine, dried over magnesium sulfate, dried over magnesium sulfate. The solvent was removed, and the residue was crystallized from diisopropyl ether to give 8-benzyloxy-4-ethoxycarbonyl-2-methylquinoline (686 mg) as solid.
