Versuchsvorschrift

A solution of 100 mg of 7-amino-N-[(4-chlorophenyl)methyl]-4-hydroxy-3-quinolinecarboxamide in 1 mL of anhydrous pyridine is treated with 0.032 mL of acetic anhydride. After 24 h, an additional 0.005 mL of acetic anhydride is added and the mixture is stirred for an additonal 48 h. The mixture is diluted with 2 mL of distilled water and the precipitate is collected by filtration. It is washed with two 1 mL portions of distilled water and dried in a stream of air. It is dried at 20 torr/75°C./16 h. The product is obtained as 78 mg of a tan solid.
