Abstract

The title compound, C₁₃H₁₃NO₃, was synthesized by acetyl­ation of ethyl 1H-indole-3-carboxyl­ate. The aromatic ring system of the mol­ecule is essentially planar, but the saturated ethyl group is also located within this plane and the overall r.m.s. deviation from planarity is only 0.034 Å. Pairs of C-HO inter­actions connect mol­ecules into chains along the diagonal of the unit cell. Mol­ecules also form weakly connected dimers via stacking inter­actions of the indole rings with centroid-centroid separations of 3.571 (1) Å. C-H inter­actions between methyl­ene and methyl groups and the indole and benzene ring complete the directional inter­molecular inter­actions found in the crystal structure.
