Reaction Steps

A solution of hydrogen chloride in ether (1 molar, 0.34 ml) was added to a mixture of 4-chloro-6,7-dimethoxy-3-fluoro-quinoline (80 mg) and 4-(2-methoxyphenoxy)-aniline (142 mg) in cyclohexanol (3 ml). The mixture was stirred and heated at 110° C. for 18 hours. The mixture was cooled to ambient temperature and then filtered. The crystals were washed with a small volume of diethyl ether and then dried to give 4-(2-methoxyphenoxy)-anilino-3-fluoro-6,7-dimethoxyquinoline (120 mg, 79%).
