Phenazine is a tricyclic heteroarene that forms the core of diverse functional molecules including DNA intercalators. However, 2,8-disubstituted phenazines are rare, and this potentially limits the medicinal development of this class of heterocycles. Here we describe the synthesis of two new members of this compound class (i.e. dimethyl phenazine-2,8-dicarboxylate and the corresponding diacid), following a synthetic route that involved inter- and intramolecular Buchwald-Hartwig N-arylations. We also detail a simple NMR-based method for proving the 2,8-disubstitution pattern, in order to counterbalance suspected structural misassignments elsewhere in the peer-reviewed and patent literature.
A Practical Procedure for Regioselective Bromination of Anilines

A highly practical procedure for the preparation of bromoanilines by using copper-catalyzed oxidative bromination has been developed. Treatment of free anilines with readily available NaBr and Na 2S 2O 8in the presence of a catalytic amount of CuSO 4·5H 2O enabled regioselective bromination.
