Copper sulfate mediates a highly selective, mild, and rapid N-acylation of various aliphatic and aromatic amines using thioacids in methanol at neutral conditions. All N-acylated products of primary and secondary amines were isolated in good yields. This method offers a simple workup, high yields, and is is not sensitive to other functional groups such as phenols, alcohols, and thiols.
