Versuchsvorschrift

2-Chloro-4,5-diiodoimidazole (354 mg) was suspended in concentrated nitric acid (d. 1.42) (5 ml), under ice-cooling, concentrated sulfuric acid (1 ml) was added, and was stirred at a room temperature for 15 hours. Reaction mixture was poured in ice-water, and ammonia water was added to adjust pH 3, the deposited matters were collected by filtration and dried, there was obtained 2-chloro-5-iodo-4-nitroimidazole (222 mg, yield: 81.2%) as yellow solid product.
