실험 절차

A mixture of 8-chloro-3-(4-methanesulfonylbenzyl)-2,4-dimethylquinolin-5-ol (0.31 g), N,N-dimethylformamide (5.0 mL), potassium carbonate (0.46 g) and bromoacetic acid methyl ester (0.35 g) was stirred at room temperature for 17 hours. The mixture was diluted with ethyl acetate and this solution washed with water and saturated aqueous sodium chloride solution and then dried over magnesium sulfate. The solvent was removed under reduced pressure and purification of the residue by column chromatography on silica gel, eluting with a mixture of toluene, dichloromethane and ethyl acetate (1:1:0 to 0:1:0 and 0:1:1 by volume) gave title compound as a white solid, 0.20 g.
