This paper describes a one-pot procedure for acetamide synthesis directly from amines and pyrimidine ester, without any catalyst or coupling agents. The inexpensive and simple reaction conditions are the most important features of this amidation. This reaction was performed with various amines, showing that long range stabilizing interactions (H-bonding and π-stacking) are the driving force for chemoselectivity.
