Abstract: The absolute configuration of the title compound, C14H13NOS, was assigned from the synthesis and confirmed by the structure determination. There are two independent mol­ecules in the asymmetric unit. The central six-membered ring of the indolizine moiety adopts an envelope conformation, with the greatest deviations from the mean planes being 0.569 (3) and 0.561 (3) Å for the indolizine bridgehead C atoms of the two mol­ecules. The benzothieno ring attached to the indolizine ring system is planar to within 0.015 (3) Å in both mol­ecules. In the crystal, weak C-H...O and C-H...[pi] inter­actions lead to the formation of a three-dimensional framework structure.
