Synthesis of 2(1H)-Pyridones From 2H-Pyran-2-ones 5-Substituted and 4,5-disubstituted 2(1H)-pyridones (13 examples) with formyl, acyl, alkoxycarbonyl, and trifluoromethyl groups in the 5 position were prepared in 16-97% yield by amination of the corresponding 2H-pyran-2-ones with hexamethyldisilazane or alkyl(trimethylsilyl)amines.
