[Antiarrhythmic amidinohydrazone substituted benzophenones. 2. Preparation and determination of configuration of (Z)- and (E)-2-amino-5-chlorobenzophenone amidinohydrazone salts].

: 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.
