N-Methyl cyclic amines readily formed quaternary ammonium salts upon treatment with iodoacetonitrile in high yields (70–96%). The latter were selectively demethylated by heating in dimethylformamide to give aminoacetonitriles in moderate to good overall yields (36–69%).

通过季铵盐选择性脱甲基合成氨基乙腈的新方法

用碘乙腈处理后，N-甲基环胺很容易形成季铵盐（70-96％）。后者通过在二甲基甲酰胺中加热选择性脱甲基，得到氨基乙腈，总收率中等至良好（36-69％）。
