Reaction Steps

2-Fluoro-4-{[6-methoxy-7-(3-morpholinopropoxy)-4-quinolyl]oxy}-aniline (30 mg) was dissolved in chloroform (3 ml) and triethylamine (0.3 ml) to prepare a solution. A solution of triphosgene (17 mg) in chloroform (0.2 ml) was then added to the solution, and the mixture was stirred at room temperature for 25 min. Next, a solution of 1-(3,4-difluorophenyl)ethylamine (14 mg) in chloroform (0.2 ml) was added thereto, and the mixture was stirred at room temperature for 5 hr. The stirred mixture was purified by chromatography on silica gel using chloroform/methanol for development to give the title compound (27 mg, yield 60%).
