Conditions

Temperature: 50 °C

Procedure

After adding dimethylformamide (8 ml), (2R)-(−)-glycidyl p-toluenesulfonate (1000 mg) and potassium carbonate (940 mg) to 4-(4-amino-3-fluorophenoxy)-6-cyano-7-hydroxyquinoline (1000 mg), the mixture was heated at 50° C. for 4 hours. Water was added to the reaction solution, extraction was performed with ethyl acetate, and then the organic layer was washed with water and saturated brine in that order and dried over anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure. The obtained crude product was purified by silica gel column chromatography (ethyl acetate) to obtain the title compound (659 mg) as light yellow crystals.
