Versuchsvorschrift

A solution of 0.95 g (3.83 mmol) of 2,4-dichloro-pyrimidine-5-carboxylic acid-tert-butylamide in 6 ml of THF is mixed at room temperature while being stirred with a suspension that consists of 1.00 g (3.86 mmol) of N-(3-amino-propyl)-3-nitro-benzenesulfonamide in 9 ml of THF/0.55 ml of triethylamine. After 19 hours, the precipitate that is formed is suctioned off and washed with ethyl acetate. The filtrate is spun in, and the residue that is formed is purified by chromatography (hexane/ethyl acetate 2:1, Flashmaster II). 0.79 g (1.67 mmol, corresponding to 44% of theory) of the product is obtained.
