실험 절차

A mixture of 3-(2,4-dichlorobenzyl)-8-fluoro-5-hydroxy-4-methyl-1H-quinolin-2-one (0.30 g), N,N-dimethylformamide (4.0 mL), potassium carbonate (0.13 g) and (S)-2-chloropropionic acid methyl ester (0.11 g) was stirred at 45° C. for 3 days. The mixture was diluted with water and extracted with ethyl acetate. The combined extracts were washed saturated aqueous sodium chloride solution, dried over magnesium sulfate and the solvent removed under reduced pressure. The residue was purified by column chromatography on silica gel, eluting with a mixture of dichloromethane and ethyl acetate (1:0 to 6:4 by volume) to afford title compound as a pale peach solid, 0.17 g.
