Abstract: The asymmetric unit of the title compound, C13H9NO3, consists of two crystallographically independent mol­ecules. In each mol­ecule, the tetra­hydro­furan (THF) ring adopts an envelope conformation with one of the methyl­ene C atoms positioned at the flap. The dihedral angles between the mean plane of the THF and the benzofuran ring system are 70.85 (5) and 89.59 (6)°. In the crystal, mol­ecules are stacked in a column along the a-axis direction through C-H...O hydrogen bonds, with columns further linked by C-H...N and C-H...O inter­actions.
