Versuchsvorschrift

A mixture of 8-chloro-3-(4-chlorophenoxy)-2,4-dimethylquinolin-5-ol (0.16 g), N,N-dimethylformamide (3.0 mL), potassium carbonate (0.20 g) and bromoacetic acid methyl ester (0.88 g) was stirred at room temperature for 15 hours. The mixture was diluted with dichloromethane, washed with water and 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 dichloromethane and ethyl acetate (1:0 to 5:1 by volume) gave title compound as an off-white solid, 0.20 g.
