Abstract
The molecule of the title compound, C(19)H(27)NO(3), is essentially planar, with all non-H atoms within 0.2 A 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 A and C-H.O > 115 degrees ), and an intermolecular C-H.O=C contact and pi-pi stacking complete the intermolecular interactions.
