Versuchsvorschrift

To a solution of 1.37 g of 3-aminobenzoic acid and 0.4 g of sodium hydroxide added to 50 ml of water was added dropwise 1.41 g of benzoyl chloride and a solution of 0.4 g of sodium hydroxide dissolved in 5 ml of water under an ice bath at the same time, and the resulting mixture was stirred at room temperature for 6 hours. The reaction solution with 1N hydrochloric acid added thereto was adjusted to pH 1, and then the precipitated solid was filtered off and collected to obtain 1.92 g of the desired product (Yield: 80%) as a white solid.
