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
Antiarrhythmic active amidinohydrazones of substituted benzophenones. Part 2: Preparation and determination of the configuration of (Z)- and (E)-2-amino-5-chlorbenzophenoneamidinohydrazone salts

, p. 828 - 833 (2007/10/02)
The configurational isomers of the 2-amino-5-chlorbenzophenoneamidinohydrazones could be obtained as TLC pure samples by fractionating crystallization of the product mixture. The determination of their configuration by comparison of the UV spectra with the corresponding oximes could be confirmed by X-ray structure analysis.

The title compounds are synthesized as a rule by condensation of substituted benzophenones and derivatives of aminoguanidine in the presence of up to 2,5 moles of an anorganic acid. They can be obtained alternatively via corresponding hydrazones, thiosemicarbazones or methylthiothiocarbonylhydrazones.
