4-[4-(4-Tert-butylphenylamino)phenoxy]-6-methoxyquinolin-7-ol (compound 21) (210 mg) was dissolved in N,N-dimethylformamide (10 ml) to prepare a solution. Potassium carbonate (500 mg) and p-toluenesulfonic acid (2S)-(+)-glycidyl (0.31 g) were then added to the solution, and the mixture was stirred at room temperature overnight. Morpholine (0.5 ml) was added to the reaction solution, and the mixture was stirred at 70° C. for additional 9 hr. Water and ethyl acetate were added to the reaction solution, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine and was dried over sodium sulfate. The solvent was removed by evaporation under the reduced pressure, and the residue was purified by thin-layer chromatography on silica gel using chloroform/acetone for development to give the title compound (180 mg, yield 64%).
