Resum
The nucleophilic displacement of bromo, alkylthio and alkylsulphonyl groups from pyridine systems by cyanamide is studied in order to obtain a previously unreported 2-cyanaminopyridine-3-carbonitrile. A one-step synthesis of the same compound by cyclization in basic medium of the non-isolated Michael adduct of (E)-1,3-diphenylpropenone and propanedinitrile is also described.
