Thionyl chloride (20 me) was added to 2.2 g of 9-acridinecarboxylic acid, followed by heating under reflux for 5 hours. After the thionyl chloride was distilled off under reduced pressure, 20 ml of methylene chloride were added further. Distillation was repeated twice under reduced pressure, whereby 2.4 g of the compound (2) were obtained (yield: stoichiometric).
