Versuchsvorschrift

To the suspension of 2,4,5,6-tetrachloro-1,3-dicyanobenzene (2.0 g, 7.52 mmol) and triethylamine (5 ml) in methyl cyanide (40 ml) is added a solution of (1R,2R)-diaminocyclohexane (0.85 g, 7.52 mmol) in methyl cyanide (10 ml). The mixture is mixed for 60 min. at 120° C., then cooled to room temperature and the water (10 ml) is slowly added. After cooling in a refrigerator the solid is recovered on a G4 filter and washed with water-methyl cyanide (1:1) and with methyl cyanide. Finally, the product is vacuum-dried on KOH tablets. 2.32 g (89%) of pale yellow powder are obtained, dec. at a temp. greater than 190° C.
