Reaktionsschritte
To a solution of 4-(1H-benzimidazol-2-yl)-furazan-3-ylamine (0.10 g, 0.497 mmol) in pyridine (5 ml) sodium in methanol (0.02 g, 0.86 mmol in 1 ml) and acrylonitrile (0.03 g, 0.39 mmol) are added sequentially at 0° C. The mixture is stirred over night. Evaporation of the solvent under reduced pressure and partitioning of the resulting residue between water and ethyl acetate followed by drying of the organic solution over sodium sulphate gives the title compound in pure form. 1H-NMR (400 MHz, d6-DMSO): 13.7 (s, 1H); 7.82 (d, 1H); 7.60 (d, 1H); 7.36 (m, 2H); 7.20 (t, 1H); 3.67 (q, 2H); 2.94 (t, 2H).
