METHOD FOR PRODUCING 2-CYANO-3-HYDROXY-N(PHENYL)BUT-2-ENAMIDES

METHOD FOR PRODUCING 2-CYANO-3-HYDROXY-N(PHENYL)BUT-2-ENAMIDES

The invention relates to a method for obtaining cyan-3-hydroxy-N-(phenyl)but-2-ene amide, whereby a phenyl-substituted 2-cyan-N-(phenyl)acetamide is converted in the presence of a base, acetic acid anhydride and at least one solvent, and the 2-cyan-3-hydroxy-N-(phenyl-derivative)but-2-ene amide obta...
