چکیده
In the title mol-ecule, C(21)H(25)NO(2), the dihedral angle between the two benzene rings is 4.8 (2)°. Both the ethyl group of the ester group and one of the ethyl groups attached to the N atom are disordered over two sites, the approximate occupancies being 66:34 and 81:19, respectively. In the cystal structure, there are no direction-specific inter-actions.
