Abstract: The asymmetric unit of the title compound, C23H23N3O2, contains two molecules in both of which, one amide N atom is in a syn position with respect to the pyridine N atom, while the other amide N atom is in an anti position (the syn--anti conformation). There are minor conformational differences between the two molecules, as reflected in the Npyridine-C-C-Namide torsion angles of -44.9 (3) and 136.0 (2)° for one molecule and 43.5 (3) and -131.1 (2)° for the other molecule. However, the two molecules show significant differences in the orientation of an ethyl group, with corresponding C-C-N-C torsion angles of 86.6 (3)° for one molecule and 79.6 (3)° for the other molecule. In the crystal, molecules are linked by weak C-H
O hydrogen bonds, forming a three-dimensional supramolecular network.
