Mode opératoire

0.5 g N-(2-bromoethyl)-4-[(4,5-dimethyl-1,3-thiazol-2-yl)diazenyl]-N-ethylaniline is dissolved in 10 ml acetonitrile followed by subsequent addition of 5.3 g 1-methyl-1H-imidazole. The reaction mixture is heated at 80° C. overnight. After cooling to room temperature, the formed precipitate is filtered off, washed with acetonitrile, and dried under vacuum at 40° C. 0.49 g of 1-{2-[{4-[(4,5-dimethyl-1,3-thiazol-2-yl)diazenyl]phenyl}(ethyl)amino]ethyl}-3-methyl-1H-imidazol-3-ium bromide are obtained as a red crystals.
