Abstract
The corresponding 2-amino derivatives of phenazinium salts were obtained by the action of dimethylamine and morpholine on N-(2-hydroxyethyl)phenazinium chloride. The subsequent exchange of the hydroxyl group for chlorine and the reductive cyclization of 2-amino derivatives of N-(2-chloroethyl)phenazinium salts leads to 4′-aminodibenzo[1′,2′-b,e]-1,4-diazabicyclo[2.2.2]octadienes, together with unsubstituted dibenzo-[b,e]-1,4-diazabicyclo[2.2.2]octadiene and the corresponding 2-aminophenazines.
