| Summary: | 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...π interactions lead to the formation of a three-dimensional framework structure.
