Abstract: In the title compound, C₂₄H₁₇NO₄, the oxetane ring deviates from planarity. The benzofuran and indole moieties are in synclinal configurations, and the attached phenyl ring forms a dihedral angle of 68.0  (2)° with respect to the oxetane ring. Intramolecular C-HO interactions stabilize the molecular structure.
