Reaction Steps

5.0 g of 4,5-dichlorophthalonitrile was dissolved in 50 ml of DMSO. 14.3 g of phenol was added and the solution was heated to 90° C. Portions of 6.9 g of potassium carbonate was added every five minutes until a total of 55.2 g had been added. The mixture was stirred at 90° C. for thirty minutes then cooled and poured into 500 ml of ice-water. The resulting solid precipitate was collected and crystallized from methanol to produce 3.6 g of product; 1H NMR (200 Mz, CDCl3) δ=7.49-7.38 (m, 4H), 7.32-7.25 (m, 2H), 7.15 (s, 2H), 7.10-7.02 (m, 4H)
