cyclic paramagnetic amidine gave nitroxides of imidazopyrimidine series. Introduction Aryl methyl ketones are known to give twice aminomethylated products under Mannich reaction conditions (1). Resulting β,β'-diaminoketones are quite able to eliminate the molecule of amine to form appropriate enone Mannichbases. The latter are known for their capability for the reaction with two equivalents of the same
