Synthesis of Novel Methoxy and Hydroxy Derivatives of 2-Phenyl-1H-benzindoles

The synthesis of novel methoxy-derivatives of 2-phenyl-1H-benzindole 3 by condensation of α-naphthylamines 1 with N-phenacyl-pyridinium salts 2 is described, as well as their conversion into the corresponding hydroxy-derivatives 5.Unexpected quinoxaline derivatives 4 were obtained when in the condensation reaction the N-nitrophenacylpyridinium salts 2d,e have been used.
