N,N-Dimethylformamide (2 ml) was added to 4-{4-[4-(tert-butyl)anilino]phenoxy}-6-methoxy-7-quinolinol (compound 21) (100 mg), potassium carbonate (167 mg), and 4-(2-chloroethyl)morpholine hydrochloride (70 mg), and the mixture was stirred at 75 to 80° C. for 6 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, and the solvent was then removed by evaporation under the reduced pressure. The crude thus obtained was purified by thin-layer chromatography on silica gel using chloroform/methanol for development to give the title compound (102 mg, yield 81%).
