| abstract |
Process for the preparation of 2-substituted 5-nitroso-4,6-diaminopyrimidines. Malonic dinitrile and amidine are nitrosated in the presence of a nitrite salt, to form the corresponding amidine salt of isonitrosomalononitrile. The latter is converted to the end product in the presence of an aprotic polar solvent by heat treatment in a basic medium. |
