Pyridinium N-(2′-azinyl)aminides:: Regioselective synthesis of 2-alkylaminoazines

The regioselective alkylation of pyridinium-N-(2'-azinil)aminides with alkyl halides under mild conditions is described. The alkylation, combined with a reduction of the N-N bond, allows an easy preparation of 2-alkylaminoazines. (C) 2000 Elsevier Science Ltd. AU rights reserved.
