In the title compound, C19H17NO3S2, the morpholine ring is in a chair conformation. In the coumarin ring system, the dihedral angle between the benzene and pyran rings is 3.9 (1)°. In the crystal, weak C—H⋯O inter­actions link the mol­ecules into corrugated layers parallel to (102). The crystal packing also exhibits π–π inter­actions, with distances of 3.644 (1) and 3.677 (1) Å between the centroids of the benzene rings of neighbouring mol­ecules.
