.The aim of the present study was to synthesis a series of phthalimides based on our previous works and examine their anxiolytic properties. Using a three steps process, phthalimides were prepared from the corresponding di-methyl phthalate derivatives. Phthalic anhydride was nitrated to produce 3-nitrophthalic acid.
I know you need two equivalents of phthalic anhydride but I am having trouble figuring out the mechanism to get CO2 and 2 molecules of
The phthalic acid is then converted to phthalic anhydride by dehydration and sublimation. This phthalic anhydride will be used in further synthesis to make phenolphthalein and phthalimide

Phthalimide is first treated with Sodium Hydroxide and then oxidised by using NaOCl or NaOBr. This is known as the Hofmann Degradation or Hofmann Amine Synthesis. Commercially, Anthranilic Acid is prepared using Phthalimide or Phthalic Anyhdride. (B) Phthalimide may also be made by fusing 500 g. (3.4 moles) of phthalic anhydride and 500 g. (4.4 moles) of ammonium carbonate which has been previously ground in a mortar.The subsequent procedure is the same as when aqueous ammonia is used. Fr
