Abstract

Abstract A simple, efficient, and new method has been developed for the preparation of N, N- dimethylamides from carboxylic acids. As described below, treatment of a variety of aromatic carboxylic acids with N, N-dimethylsulfamoyl imidazole or N, N-dimethylsulfamoyl chloride in the presence of a mixture of methanesulfonic acid/phosphorus pentoxide (2: 1, v/w) proceeded effectively to afford the corresponding N, N-dimethylamides in moderate to ...
