Abstract
1,147,555. 1 - Cyano - 2,4,5 - trichloro- and 1,2,4,5 - tetrachloro - imidazole. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 6 Feb., 1967 [8 Feb., 1966; 12 Oct., 1966], No. 5534/67. Heading C2C. [Also in Division A5] The invention comprises 1-cyano-2,4,5-trichloroimidazole. The compound is prepared by reacting 1,2,4,5-tetrachloroimidazole with anhydrous cuprous cyanide at a temperature of at least 110‹ C., or by reacting 2,4,5-trichloroimidazole with an alkali metal alcoholate. in the presence of an inert polar solvent and in the absence of moisture and then reacting the resulting 2,4,5-trichloroimidazole salt solution with cyanogen chloride or bromide at 0-30‹ C. The 1,2,4,5-tetrachloroimidazole starting material may be obtained by chlorination of an imidazole salt (e.g. the hydrochloride) in the presence of a chlorinated hydrocarbon solvent and under anhydrous conditions.
