Methods for the synthesis of N-substituted pyridinium compounds by using an N-heteroaryl substituted pyridinium salt (Zincke salt) and reacting it with a nucleophilic amine are provided. Novel purine-substituted pyridyl compounds, which may be useful reagents in the above reaction, are also disclosed.
