Methyl 1-methyl-1H-indole-3-carboxylate

Abstract

The title indole derivative, C11H11NO2, was synthesized from 1-methyl-1H-indole-3-carboxylic acid and methanol. The molecule is planar as it is situated on a mirror plane present in the space group Pbcm. In the crystal, molecules form three kinds of intermolecular C—H...O hydrogen bonds, resulting in a sheet structure in the ab plane. Parallel sheets interact by C—H...π stacking, stabilizing the crystal packing.
