Reaction Steps

To the PPSE solution was added 15.0 g of 4,4'-dibromodiphenic acid, 8.11 g of o-phenylene diamine (recrystallized from methylene chloride and charcoal). This mixture was rapidly heated to 160° C. and maintained there for 20 hours. The solution was cooled, then poured into 2 1 of 10% NaHCO3 solution. The product was filtered, washed with 300 ml of hot methylene chloride, then extracted using a Soxhlet extractor using 10% NaHCO3 overnight. The product was dried then recrystallized from ethanol to give 11 g of white crystals, mp 326° C.-328° C. Analysis calculated for C26H16N4Br2 : C, 57.38; H, 2.96; N, 10.29. Found: C, 57.81; H, 3.04, N, 10.30.
