A process for obtaining an amide of the general formula R-(CO)—NH—CH
2
—X involves contacting a nitrile of the general formula R-CN with:
a) an acid; and
c) an alkoxy-containing compound comprising at least one alkoxy functionality of the general formula —OCH
2
-X;
wherein R is hydrogen or an alkyl, cycloalkyl, alkenyl, cycloalkenyl, alkynyl, aryl, or heterocyclic substituent, which substituents can be substituted or unsubstituted; wherein X is hydrogen or a radical having the general formula —CHR
