In the title compound, C13H16ClNO, the acetylindoline moiety is roughly planar (r.m.s. deviation = 0.0048 ). The chloropropyl group is out of the plane and is statistically disordered over two positions. Indeed, the Cl and CH3 groups located on the stereogenic carbon exchange with each other. The whole crystal is a racemate. Non-classical C—H...O hydrogen bonds between symmetry-related benzene rings stabilize the crystal structure.
