Procedure

2-Chloro-4-[(6,7-dimethoxy-4-quinazolinyl)oxy]-aniline (214 mg) was dissolved in chloroform (5 ml), and 2,4-difluorophenyl isocyanate (180 μl) was then added to the solution. The mixture was allowed to react at 70° C. for 4 hr, and a large amount of ether was added to the reaction solution. The resultant precipitate was collected by suction filtration to give 146 mg (yield 46%) of the title compound.
