Versuchsvorschrift

To a solution of 4-amino-3-nitro-benzoic acid (546 mg). EDCI (576 mg) and HOBt (405 mg) in DMF (8 mL) was added 3,4-dimethylaniline (363 mg) and the mixture was stirred at room temperature for 3 h. The mixture was poured into water and exreacted with EtOAc. The organic phase was washed with water (2×) and was dried over sodium sulfate. The solvent was concentrated to approximately 10 mL and the resulting precipitate was filtered, washed with EtOAc and dried under reduced pressure to give 4-amino-N-(3,4-dimethyl-phenyl)-3-nitro-benzamide as a yellow solid, mp=192-195° C.; MS (m/z) 284 (M−1).
