Bottom Line: The asymmetric unit of the title compound, C(19)H(20)N(2)O(3), contains two independent mol-ecules in both of which the pyrrolidine ring adopts an envelope conformation, but with a C atom as the flap in one mol-ecule and the N atom in the other.The pyran ring adopts a half-chair conformation in both mol-ecules.In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds and C-H⋯π inter-actions.
