Procedure
2-Aminobenzophenone (33 g) and 2,5-dichloroacetophenone (32 g) were placed in a flask together with 2.5 g of toluenesulfonic acid monohydrate. The mixture was heated and stirred at 160°-170° C. for 24 hours. The resulting mixture was diluted with ethanol (300 ml). The crystals was filtered to give 63 g crude product, which was treated with charcoal and recrystallized first from ethanol, followed by recrystallization from hexane and ethyl acetate to give monomer as white crystals (65%).
