Reaction Steps

N-{4-[(6,7-Dimethoxy-4-quinolyl)oxy]phenyl}thiourea (50 mg) was dissolved in dimethylformamide (5 ml) to prepare a solution. Triethylamine (43 mg) and 3-bromo-2-butanone (43 mg) were added to the solution, and the mixture was stirred at room temperature for 3 hr. Water and ethyl acetate were added to the reaction solution, and the mixture was extracted with ethyl acetate. The extract was then washed with saturated brine and was dried over anhydrous sodium sulfate, and the solvent was removed by evaporation under the reduced pressure. The crude thus obtained was purified by column chromatography on silica gel using chloroform/methanol for development to give the title compound (42 mg, yield 73%).
