Vorschrift

In a 2-liter eggplant type flask, 62.8 g of N-phenyl-iminodiacetic acid was charged and dissolved in 500 mL of toluene under a nitrogen gas stream, to which was then added 32.0 g of acetic anhydride. The mixture was refluxed under heating and stirred. One hour thereafter, the reaction mixture was cooled to room temperature, to which was then 3 L of hexane with stirring to undergo deposition. A reaction product was filtered to obtain 52.0 g of N-phenyliminodiacetic anhydride.
