Versuchsvorschrift

22 g (105.2 mmol) of ammonium 3-nitrophthalamidate (1a) were treated with stirring with 165 ml of sodium hypochlorite solution. After 5 minutes, a solution of 8.8 g of sodium hydroxide in 22 ml of water was added and the mixture was then stirred at 70° C. for 1 h. The suspension was poured into 500 ml of water with stirring. The resulting clear solution was acidified with concentrated HCl. The precipitate was filtered off and dried in a desiccator. Yield: 9.68 g (51%).
