The substitution of the dialkylamine residue of N-(dialkylaminomethyl) amides with nucleophiles leading to the formation of the amidomethyl compounds, reported in several papers by Hellmann, et al. has been shown not to occur with sulfides and cyanide under the condition of heating in methanol preferably in the presence of sodium hydroxide, whereas the substitution of the amide residue is chiefly effected. By similar manners the substitution reactions of N-(α-dialkylaminobenzyl) amides with sulfides and cyanide have been also realized.
赫尔曼等人在多篇论文中报告了 N-(二烷基氨基甲基)酰胺的二烷基胺残基与亲核物的取代反应,导致酰胺甲基化合物的形成,但事实证明,在甲醇中加热(最好是在氢氧化钠存在下)的条件下,硫化物和氰化物不会发生取代反应,而酰胺残基的取代反应则主要发生。通过类似的方法,还实现了 N-(α-二烷基氨基苄基)酰胺与硫化物和氰化物的取代反应。
