A process for the preparation of a 2-cyano-2-oximino-acetamide derivative of the formula ##STR1## in which R.sup.I is alkyl or other organic radical, R.sup.II is hydrogen or alkyl, R.sup.III is hydrogen, alkyl or other organic radical which comprises reacting a 2-cyano-2-oximino-acetamide of the formula ##STR2## with a base B at a temperature between 0.degree. C. and 100.degree. C., to produce a salt of the formula ##STR3## in which B represents one equivalent of an organic of inorganic base, and reacting such salt with an alkylating agent of the formula ##STR4## in which X is halogen, methane- or p-toluenesulphonate or methyl sulphate, at a temperature between 0.degree. C. and 150.degree. C.
