Versuchsvorschrift

A mixture of Z-α-methoxyiminopyrazineacetonitrile (4 g), acetic acid (15 ml) and 30% hydrogen peroxide in water (15 ml) was heated at a temperature of 70° C. over one night. The reaction mixture was concentrated and treated with water and chloroform. The chloroform layer was separated and dried over magnesium sulphate. Evaporation of the solvent and successive crystallization of the residue from alcohol afforded Z-α-methoxyimino-2-pyrazineacetonitrile-4-oxide, m.p. 144°-145° C.
