Versuchsvorschrift

To a mixture of 2-nitroaniline (1.38 g) and triethylamine (1.67 ml) in dichloromethane (30 ml) were added 4-nitrobenzoyl chloride (1.85 g) and the solution was stirred at ambient temperature for 4 hours. The solution was washed successively with 1N hydrochloric acid, saturated aqueous sodium hydrogencarbonate, water and brine, and the organic layer was dried over magnesium sulfate. The solvent was evaporated in vacuo and the residue was solidified with n-hexane to give 2-nitro-N-(4nitrobenzoyl)aniline (1.82 g).
