The asymmetric unit of the title compound, C19H20N2O3, contains two independent molecules in both of which the pyrrolidine ring adopts an envelope conformation, but with a C atom as the flap in one molecule and the N atom in the other. The pyran ring adopts a half-chair conformation in both molecules. In the crystal, molecules are linked via C—H...O hydrogen bonds and C—H...π interactions.
