A practical amidation reaction for the synthesis of primary amides is presented, in which the simple NH4Cl was identified as a practical and convenient amine source. A series of aromatic and aliphatic acid chlorides were successfully compatible with this protocol, affording the corresponding amides in good to excellent yields, which provides a rapid and reliable approach to amides from simple starting materials. Introducing the appropriate N-methyl pyrrolidone (NMP) into the system as solvent and acid-binding reagent plays a key role to avoid the use of stoichiometric amounts of base.

Key words: ammonium salts, amidation, primary amides, acid chlorides, N-methyl pyrrolidone
