2-(2,5-Dimethoxyphenyl)pyrrole-3-carbonitrile

Abstract

The Cadogan reaction of 2-aryl-3-nitropyridines leads to δ-carbolines. The title compound is a side product in this reaction, generated via a ring opening of a nitrene and cyclization. A crystal structure analysis gives an enormous unit cell.
