A number of quaternary salts of ethyl γ-pyridylbutyrate and diethyl β-pyridylethylmalonate undergo the Kost-Sagitullin reaction to give N-methyl-2-quinolone and 3-methylaminocarbamoyl-N-methyl-2-quinolone.Rearrangement in the presence of excess aliphatic amines is accompanied by an efficiently proceeding trans-amination.
