Reaction Steps

A mixture of 4-[1-(4-bromophenacyl)-1H-benzimidazol-2-yl]-furazan-3-ylamine (0.083 g, 0.21 mmol, prepared according to Example 1), sodium bicarbonate (0.021 g, 0.25 mmol) and hydroxylamine hydrochloride (0.014 g, 0.21 mmol) in ethanol (5 ml) is refluxed for 20 hours. Partitioning of the reaction mixture between ethyl acetate and water, separation of the organic phase followed by drying and evaporation of the solvent gives the crude product. Purification by chromatography on silicagel yields the title compound as an E/Z-mixture, m.p. 198-201° C.
