Procedure
A solution of 4-chloro-6-methoxy-7-(2-methoxyethoxy)quinoline hydrochloride (304 mg, 1 mmol), (prepared as described for the starting material in Example 5), 2-fluoro-5-hydroxy-4-methylaniline (155 mg, 1.1 mmol), (prepared as described for the starting material in Example 1), in 2-pentanol (15 ml) was heated at reflux for 15 hours. The precipitate was collected by filtration, washed with isopropanol and dried under vacuum to give 4-(2-fluoro-5-hydroxy-4-methylanilino)-6-methoxy-7-(2-methoxyethoxy)quinoline hydrochloride (205 mg, 50%).
