The title mol­ecule, C19H18N2O2, is built up from three fused rings, viz. phenyl, pyrrole and cyclo­hexane, linked to a nitro­benzyl group. The C atom bearing the nitro­benzyl group is chiral and the compound is a racemate (R/S). The dihedral angle between the nitro­benzyl and indole rings is 57.49 (5)°. The cyclo­hexane ring adopts a slightly distorted chair conformation.
