Abstract
These compounds are used in medicine and are an interim product for extracting f S-heteryl-N<1>-N<3>-replaced propioamidrazones, which exhibit a radio protective activity. They have a formula<IMAGE>Where R1 is phenyl, R2 is alkyl with 1 to 6 carbon atoms or benzyl. The method for their extraction relies on the consecutive interaction of acrylonitrile with iron trichloride, replaced halogenide and N-replaced hydrazine upon cooling.
