[Antiarrhythmic active amidinohydrazones of substituted benzophenones. 3. The isomerization of (E)-2-amino-5-chlorobenzophenone amidinohydrazones].
The isomerization of the title compound in a preparative scale can be realized by acetylation/deacetylation or by influence of protons in dimethylformamide. The title compound is obtained als main product of the condensation of 2-amino-5-chlorbenzophenone and aminoguanidine if the reaction is carried out in the presence of formaldehyde.
