A mixture of 9,10-dihydro-9-oxo-4-acridinecarboxylic acid (1.5 g) and 1-hydroxybenzotriazole (1.1 g) in DMF (50 ml) was stirred at room temperature for 10 min. The product of part (ii) above (1.5 g) was then added followed by dicyclohexylcarbodiimide (1.3 g), and the mixture was stirred at room temperature for 16 h and then filtered. The filtrate was concentrated in vacuo, treated with water and extracted with dichloromethane. The combined, dried organic extracts were concentrated to give the title compound (0.5 g) which was recrystallised from acetonitrile, MP 126°.
