Abstract

1. A process for producing 2-substituted 5-nitroso-4,6-diamino pyrimidine of the general formula : see diagramm : EP0115325,P5,F1 wherein R is aryl, alkyl, alkylthio, amino, amino substituted by one or two C1 to C4 alkyl groups, or arylalkyl, which comprises the steps of reacting malonic dinitrile with an amidine or guanidine of the general formula : see diagramm : EP0115325,P5,F2 wherein A is Cl, 1/2 SO4 , HSO4 , NO3 , acetate, or 1/3 PO4 , and R has the meaning stated above, in water or alcohol in an acid milieu and in the presence of a nitrite salt to form the respective amidino or guanidino salt of isonitroso-malonitrile, and converting the salt thus obtained in a manner known per se by thermal treatment in dimethyl formamide or a pyridine base in a basic milieu to produce the respective 2-substituted 5-nitroso-4,6-diamino pyrmidine.
