The process of the invention for preparing a N-(2-substituted aminoethyl)amide of the formula: ##STR1## comprises contacting one or more compounds of the formula: ##STR2## with an amine of the formula: ##STR3## wherein A is nitrogen or a quaternary nitrogen of the formula: ##STR4## wherein B is ##STR5## when A is nitrogen and B is ##STR6## when A is IV; wherein X.sup..crclbar. is a counterion; b is zero or one; and R.sub.1 -R.sub.9 are as defined in the specification. In a preferred embodiment, the process is catalyzed by a Lewis acid or a protonic acid with a non-nucleophilic counterion.
发明制备式为N-(2-取代氨基乙基)酰胺的方法包括将一个或多个化合物的式子:##STR2## 与式子为:##STR3## 的胺接触,其中A是氮或式子:##STR4## 的季铵氮,其中B是当A为氮时为:##STR5##,当A为IV时为:##STR6##,其中X.sup..crclbar.是一个计数离子,b为零或一,R.sub.1-R.sub.9如规范所定义。在首选实施例中,该过程由一个Lewis酸或质子酸催化,其具有非亲核计数离子。
