The preparation of amides from a carboxylic acid (aliphatic or aromatic) and an amine (primary or secondary) by a microwave-mediated process was previously studied and the conditions used gave good yields with primary amines and lower yields for hindered amines. [9] The use of imidazole to promote reaction of amines with sterically hindered carboxylic acids gave interesting results under mild irradiation conditions. [10] An efficient microwave energy absorption was ...
