Versuchsvorschrift

Under a nitrogen atmosphere, triethylamine (0.546 g, 5.4 mmol) was added to 2-nitro-5-piperazin-1-yl-phenylamine (1.0 g, 4.5 mmol) in dry DMF (8 mL) and the mixture was cooled in an ice water bath. Dimethylcarbamyl chloride (0.581 g, 5.4 mmol) was added slowly to this reaction mixture via syringe and the mixture was brought up to room temperature and stirred overnight. After overnight stirring, the reaction mixture was slowly poured into cold water (100 mL) and stirred for 1 hour resulting in the solidification of the product. This was filtered, dried give the product, 4-(3-Amino-4-nitro-phenyl) -piperazine-1-carboxylic acid dimethylamide, as a yellow solid, 1.2 g (92.4% yield), which was used without any further purification.
