Versuchsvorschrift
Using an analogous procedure to that described in Example 25, 4-chloro-6-methoxy-7-(2-methoxyethoxy)quinoline hydrochloride (500 mg, 1.64 mmol), (prepared as described for the starting material in Example 5), was reacted with 4-chloro-2-fluoro-5-hydroxyaniline (270 mg, 1.64 mmol), (as described in EP 61741 A2), for 5 hours to give 4-(4-chloro-2-fluoro-5-hydroxyanilino)-6-methoxy-7-(2-methoxyethoxy)quinoline hydrochloride (475 mg, 67%).
