A mixture of 18.85 g of 9-anthroic acid and 60 ml of thionyl chloride is heated under reflux for 1 hour. The excess thionyl chloride is removed under vacuum (30 mm; 90° bath temperature); 50 ml of toluene is added and the mixture is concentrated again. This operation is repeated once more to give 20.6 g of 9-anthroyl chloride as a very moisture-sensitive, yellow solid.
