실험 절차

25.3 g of 1-nitroanthraquinone (99% pure) in 120 ml of p-cymene are boiled together with 29.8 g of cyclohexylamine (molar ratio 3:1) for 2 hours under reflux. After cooling the reaction mixture, 150 ml of petroleum ether are added, the mixture is filtered and the residue is washed with petroleum ether and dried. 28.1 g (94% of theory) of cyclohexylamino-anthraquinone are obtained. No further starting material can be detected by means of thin layer chromatography.
