Versuchsvorschrift

A mixture of 52 g (0.33 mole) of 2-chlorobenzoic acid, 82 g (0.66 mole) of 4-methoxyaniline, 46 g (0.33 mole) of potassium carbonate, 5 g (0.025 mole) of cupric acetate and 150 ml of dimethylformamide was heated at reflux for two hours. The reaction mixture was cooled, 300 ml of water added and the mixture filtered. The filtrate was acidified with 50 ml of 6N hydrochloric acid, and the resulting solid was collected by filtration and recrystallized from acetonitrile to give 61 g of 2-(4-methoxyphenylamino)benzoic acid.
