Participants

Reaction Steps

A solution of 109 g (0.5 mol) of 4,5-dichloro-2-dichloromethylene-imidazole in 125 ml of dioxane was added dropwise in the course of about 10-15 minutes to a mixture of 81 g (0.5 mol) of finely powdered 2,6-dichloroaniline, 500 ml of water and 75 g (about 0.75 mol) of 37% strength aqueous hydrochloric acid at 55°-60° C., while stirring. After stirring for about a further 2 hours, the product was filtered off, washed with water and dried. 159 g (92% of theory) of 4,5-dichloro-imidazole-2-carboxylic acid N-(2,6-dichlorophenyl)-imide-chloride were obtained. Long needles with a decomposition point of about 200° C. from acetonitrile or from chloroform.
