Versuchsvorschrift

5.0 g of 4-hydrazinobenzoic acid are dissolved in 70 ml of ethanol and 3 ml of concentrated H2SO4. The mixture is heated at reflux for five hours, the ethanol is evaporated, the residue is then taken up in a saturated K2CO3 solution and then extraction is carried out with AcOEt. 5.9 g of the expected compound are obtained in the form of a powder.
