Abstract: In the title compound, C27H24N2O3, the pyrroldine ring adopts a twist conformation, while the six-membered pyranone ring of the coumarin ring system is in a sofa conformation. In the crystal, pairs of N-H...O hydrogen bonds link the molecules into inversion R22(8) dimers. These dimers are further connected via C-H...O hydrogen bonds.
