| 3-Nitrophthalic anhydride Usage And Synthesis |
| Chemical Properties | Beige to yellow crystalline powder | | Uses | An intermediate for the synthesis of a benzimidazole PARP inhibitor I (succinate salt) (ABT-472). Reactions with aminoquinazolinones yield phthalimidoquinazolinones. | | Uses | 4-Nitrophthalic Anhydride is an intermediate for the synthesis of the benzimidazole PARP inhibitor I, ABT-472. It reacts with aminoquinazolinones to yield phthalimidoquinazolinones. | | Preparation | 3-Nitrophthalic anhydride can be prepared by heating 3-nitrophthalic acid under various conditions and by the action of acetic anhydride, essentially as in the procedure described. The direct nitration of phthalic anhydride yields 3-nitrophthalic anhydride together with the isomeric 4-nitro compound. | | Purification Methods | Crystallise it from *C6H6, *C6H6/pet ether, Me2CO, AcOH, or Ac2O (m 164-165o). Dry it at 100o. [Beilstein 17 III/IV 6149, 17/11 V 266.] |
