Procedure

2-chloro-4-[(6,7-dimethoxy-4-quinazolinyl)oxy]-aniline (200 mg) was dissolved in chloroform (5 ml) and triethylamine (1 ml), and a solution of triphosgene (179 mg) in chloroform was then added to the solution. The mixture was stirred at room temperature for 30 min. Next, ethylamine hydrochloride (246 mg) was added to the reaction solution, and the mixture was stirred at room temperature overnight. A saturated aqueous sodium hydrogencarbonate solution was added to the reaction solution, and the mixture was extracted with chloroform. The chloroform layer was dried over anhydrous sodium sulfate. The solvent was removed by distillation under the reduced pressure. The residue was purified by HPLC by development with chloroform/methanol to give 159 mg (yield 65%) of the title compound.
