Reaction Steps
2-(5-Choro-2-benzimidazolyl) amino-2-imidazoline dihydrochloride (3.1g, 0.01 mol) in concentrated hydrochloric acid (25 ml) was treated with hydrogen peroxide (10%, 3.4ml) then heated to 80°C, maintained at this temperature for 15 minutes and then allowed to cool to room temperature. Recrystalisation of the resulting precipitate from water gave 2-(5,6-dichlorobenzimidazolyl) amino-2-imidazoline hydrochloride (0.46g, 15%) m.p. 279°-281°C.
