Abstract: In the title compound, C₂₅H₂₁NO₂, the coumarin moiety is planar and the attached dimethylamino group is twisted around the N-C bond. The dihedral angle between the two phenyl rings is 75.45  (9)°. The crystal structure is stabilized by weak intermolecular C-HO interactions and van der Waals forces.
