Versuchsvorschrift

A mixture of 5 g of iron dust, 0.5 g of acetic acid and 3.5 ml of water was refluxed under heating for 30 minutes, allowed to cool at 80° C. and mixed with 14 ml of 2-propanol and gradually mixed with 4.22 g of 4, 6-bis (dimethylamino)-5-nitropyrimidine. The resultant mixture was stirred at the same temperature for 1 hour, allowed to cool at 40° C., mixed with a solution of 1.5 g of potassium carbonate in 2.5 ml of water and stirred for 1 hour. Acetone was added to the mixture, which was filtered through Celite. The filtrate was concentrated in vacuo, and the residue was mixed with water and shaken with ether. The organic layer was washed with water and saturated saline in order, dried over anhydrous sodium sulfate and the solvent evaporated to give 3.32 g of the titled compound.
