Unlike conventional amide synthesis, a decarboxylative amidation of aryl/heteroarylacetic acids by reaction with NHS and tert-butyl nitrite has been reported to afford both aliphatic and (hetero)aromatic amides in satisfactory yields. Mechanistic studies revealed a previously unexplored pathway for the formation of an activated ester through the generation and subsequent reactions of traceless α-functionalized benzylic radicals, which upon subsequent one-pot reaction with amines form the amides. A gram-scale synthesis of Moclobemide indicates the practical applicability.
