実験手順
A mixture of 2-cyclopropyl-8-fluoro-4-methyl-3-(4-pyrazol-1-ylbenzyl)quinolin-5-ol (0.064 g), (N-dimethylformamide (0.86 mL), potassium carbonate (0.071 g) and (R)-2-chloropropionic acid methyl ester (0.032 g) was stirred at 40° C. for 3 days. The mixture was cooled to 0° C., diluted with water (40 mL) and extracted with ethyl acetate (3×10 mL). The combined extracts were washed saturated aqueous sodium chloride solution, dried over magnesium sulfate and concentrated under reduced pressure. Purification of the residue by column chromatography on silica gel, eluting with a mixture of ethyl acetate and cyclohexane (0:1 to 4:6 by volume) gave title compound as a colourless oil (0.033 g).
