実験手順

A suspension of 3-amino-2-(1H-benzimidazol-2-yl)-1,2,4-triazole (0.15 g, 0.75 mol), 3,4-dimethyl phenacyl bromide (0.204 g, 0.9 mmol) and dry potassium carbonate (0.258 g, 1.87 mmol) is stirred at room temperature for 16 hours. The mixture is diluted with water and the product extracted with ethyl acetate. The product is purified by chromatography on silicagel. M.p. 190-193° C., 1H-NMR (400 MHz, d6-DMSO): 7.84 (m, 1H); 7.77 (m, 3H); 7.65 (m, 2H); 7.50 (s, 1H); 7.33 (d, 1H); 6.22 (s, 2H); 2.30 (s, 6H).
