Abstract
In the title indoline compound, C19H14N2O3S, the pyrrolidine ring adopts an envelope conformation with the four-connected (spiro) C atom as the flap [displacement = 0.148 (3) Å]. The mean plane formed through the indoline unit is inclined at dihedral angles of 89.92 (16) and 59.54 (12)° with the thiazole and phenyl rings, respectively; the dihedral angle between the latter rings is 9.55 (14)°. In the crystal, pairs of intermolecular C—H⋯O hydrogen bonds link neighbouring molecules into inversion dimers, producing R 2 2(6) hydrogen-bond ring motifs. Weak intermolecular C—H⋯π as well as π–π interactions [centroid–centroid distance = 3.4041 (15) Å] further consolidate the crystal structure.
