An efficient method for the synthesis of simple and sterically hindered carboxamides from various carboxylic acids and amines using tetrabenzylpyrophosphate (TBPP) as a coupling agent in the presence of 4-(dimethylamino)pyridine (DMAP) is described. The reaction is operationally straightforward, proceeds under mild conditions at room temperature, and affords the desired product in high yield.
