Procedure

13.54 g of 3,5-dibromo-4-nitropyrazole, 11.1 g potassium carbonate, 0.8 g of potassium iodide and 6.6 g α, α′-dibromo-m-xylene are heated to 100° C. in 40 ml of dimethyl formamide. After 50 minutes the reaction mixture is allowed to cool and poured into 400 ml water. The precipitate is filtered, washed with water and dried in vacuum.
