Participants

Conditions

Temperature: 100 °C

Procedure

To a solution of 0.20 mole of 4-amino-3',4'-dicarboxybenzophenone and 0.10 mole of 2-diphenylamino-4,6-dichloro-s-triazine in 300 ml of NMP is added 0.60 mole of potassium carbonate. The reaction mixture is heated at 100°C for 24 hours and then treated essentially as in Example 1 to give 2-diphenylamino-4,6-bis-{4'-(3",4"-dicarboxybenzoyl)-anilino}-s-triazine. The tetraacid is heated in refluxing nitrobenzene essentially as in Example 1 to yield the corresponding dianhydride.
