Nucleophilic Displacement of N-Aryl and Heteroaryl Groups. Part 5. Conversion of 2-Aminopyridines into 2-Pyridones

2-Ethoxycarbonyl-1-(2-pyridyl)pyridinium cations (3) (easily prepared from 2-aminopyridine and the appropriate pyrylium salt) are converted by dilute NaOH at 25 deg C into 1-(substituted 2-pyridylcarbonyl)-2-pyridones (7).Compounds (7) are readily hydrolysed to 2-pyridones.
