実験手順
A 15 g portion of 6-ethyl-1,2-dihydro-2-oxo-5-(n-propanoyl)-nicotinic acid was heated in an oil bath at 235°-240° C. for 5 hours, cooled and the reaction mixture dissolved in hot ethanol, treated with decolorizing charcoal and filtered. The filtrate was evaporated in dryness and the residue recrystallized from isopropyl alcohol to yield 8.2 g of 6-ethyl-5-(n-propanoyl)-2(1H)-pyridinone, m.p. 138°-140° C.
