A simple catalyst- and metal-free protocol enables a chemoselective transamidation of activated secondary amides in ethanol as solvent under mild conditions. A wide range of amines, amino acids, amino alcohols are tolerated in this methodology. The transamidation reaction was successfully extended to water as the medium as well.
