The molecule of the title compound, C19H27NO3, is essentially planar, with all non-H atoms within 0.2 Angstrom of the nine-membered indole plane, except for the three tert-butyl C atoms. The C-5 pentyl chain is in an extended conformation, with three torsion angles of 179.95 (13), 179.65 (13) and -178.95 (15)degrees (the latter two angles include the C atoms of the C-5 chain only). Three intramolecular C-H...O=C contacts are present (C...O<3.05 angstrom and C-H center dot center dot center dot O>115degrees), and an intermolecular C-H...O=C contact and pi-pi stacking complete the intermolecular interactions.
