Reaction Steps

2-Chloro-4-[(6,7-dimethoxy-4-quinolyl)oxy]aniline (100 mg) was dissolved in chloroform (10 ml) and pyridine (0.1 ml) to prepare a solution. A solution of triphosgene (45 mg) in chloroform was then added to the solution, and the mixture was stirred at room temperature for 10 min. Next, 2-amino-4-methylthiazole (38 mg) was added thereto, and the mixture was further stirred at room temperature overnight. Iced water was added to the reaction solution, and the mixture was extracted with chloroform. The organic layer was washed with water and saturated brine and was then dried over anhydrous sodium sulfate. The dried organic layer was filtered and was then concentrated. Ether was added to the residue for crystallization, and the crystal was collected by filtration. The crystal was purified by chromatography (chloroform:acetone=2:1) to give 90 mg of the title compound.
