Procedure: To the slurry of 2,4,5,6-tetrachloro-1,3-dicyanobenzene (2.0 g, 7.5 mmol) in acetonitrile (40 ml) triethylamine (5.0 ml) is added, then 1,2-diaminocyclohexane (0.86 g, 7.5 mmol) and the reaction mixture is heated under reflux for 1 h. It is cooled to ambient temperature, then deposited on ice for few hours, and the crystalline product is collected on filter. 2.32 g (89%) of the title product as pale-yellow powder are obtained. under reflux for 1 h deposited on ice for few hours the crystalline product is collected on filter

Procedure: 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. The mixture is mixed for 60 min. at 120° C. After cooling in a refrigerator the solid is recovered on a G4 filter washed with water-methyl cyanide (1:1) and with methyl cyanide Finally, the product is vacuum-dried on KOH tablets
