Reaction of 7-azaindole (azinH) and 1,2,4,5-tetramethylbenzene (durene) in the presence of erbium metal and mercury at 170°C under vacuum induced an unusual C-C bond formation between a methyl group of durene and C3 of two azinH molecules yielding bis(1H-7-azaindol-3-yl)(2,4,5-trimethylphenyl)methane {2: IUPAC name 3-[1H-pyrrolo[2,3-b]pyridin-3-yl(2,4,5-trimethylphenyl)methyl]-1H- pyrrolo[2,3-b]pyridine}. The structure of 2 was established by X-ray crystallography and supported by IR, NMR and mass spectroscopy.
