In the title compound, C33H23ClN4O3S·CHCl3, the thiazole ring adopts an envelope conformation with the N atom as the flap, and the pyrrolidine ring adopts a half-chair conformation. The thiazole ring mean plane makes a dihedral angle of 59.31 (1)° with the pyrrolidine ring mean plane, 71.67 (1)° with the chromene ring and 82.59 (1)° with the chlorobenzene ring. An intramolecular C—HN hydrogen bond occurs. In the crystal, a second C—HN hydrogen bond links the main and solvent molecules. The solvent chloroform molecule is disordered about two positions with an occupancy ratio of 0.508 (14):0.492 (14).
