Versuchsvorschrift

After adding methanol (48 ml) and 2N aqueous sodium hydroxide (16 ml) to methyl 4-(3-chloro-4-(((cyclopropylamino)carbonyl)amino)phenoxy)-7-methoxy-6-quinolinecarboxylate (2.87 g, 6.50 mmol), the mixture was stirred at room temperature for 1.5 hours and at 60° C. for 15 minutes. The reaction solution was allowed to cool to room temperature, and after neutralization by addition of 1N hydrochloric acid, the methanol was distilled off and the precipitated light brown crystals were filtered out, thoroughly washed with water and dried at 70° C. to obtain the title compound (2.628 g, 6.14 mmol, 94.6%).
