摘要：
This article describes a convenient method for the synthesis of 5-aryl-6-methyl-2,2 '-bipyridines through the direct introduction of a methyl group at the C5-position of 1,2,4-triazine moieties. At first 1,2,4-triazine precursors are synthesized for this purpose. The reaction proceeds through S-N(H)/S-N(ips)degrees substitution and subsequent aza-Diels-Alder reaction. In addition, mono- and dibromomethyl-substituted 2,2'-bipyridines are also synthesized to confirm the applicability of the present method.
