Participants

Reaction Steps

0.11 g (1 mmol) of ethyl chloroformate is added, while stirring at -15° C., to a solution of 0.57 9 (1 mmol) of N-(4-carboxyphenyl)-N-(4-toluenesulfonyl)acridine-9-carboxamide hydrobromide and 0.21 g (2 mmol) of triethylamine in 25 ml of anhydrous tetrahydrofuran. The mixture is stirred at the same temperature for 1 hour and then 0.12 9 (1 mmol) of N-hydroxysuccinimide is added. After a further hour, the mixture is left to stand at room temperature for 15 hours. It is evaporated in vacuo, the residue is taken up in ethyl acetate, and the solution is washed with water, sodium bicarbonate solution and water and dried over sodium sulfate. Evaporation yields 0.42 g (70.8% of theory) of the desired product.
