Abstract
PURPOSE: To obtain the title compound useful as a raw material for various medicines, in high yield and purity, by reacting diaminomaleonitrile with cyanogen chloride, using water as a reaction medium.
CONSTITUTION: One mole of diaminomaleonitrile is reacted with 1W1.5mol of cyanogen chloride in an aqueous medium, preferably at a temperature of -10W +80°C, to obtain 2-amino-4,5-dicyanoimidazole of the formula. Cyanogen chloride is preferably used in the form of an aqueous reaction mixture produced by blowing chlorine into an aqueous prussic acid. The resulting liquid adjusted to pH 0.1W7 after the reaction improves the purity of the product.
USE: Diazodicyanoimidazole produced by the diazotation of this compound is useful as a raw material for medicines, agricultural chemicals, and dyes.
