A versatile and efficient one-pot protocol has been developed for the synthesis of amides from easily accessible carboxylic acids and amines by employing trimethylsilyl azide as a promoter at room temperature. This reaction proceeds via an in situ generated acyl azide intermediates followed by the nucleophilic substitution of amines. Notably, most of the desired amides were obtained by simple filtration in excellent yields. The significant advantages like metal-free mild reaction conditions, higher yields, easily removable volatile byproducts, operational simplicity, and broad substrate scope make the transformation a useful contribution for the synthesis of biologically important amides.
