Abstract: The mean planes of the propyl chain and carboxylate group of the ethoxycarbonyl substituent are almost orthogonal to the virtually planar dihydroquinoline bicyclic framework of the title compound, C₁₈H₁₉N₃O₄ [dihedral angles 89.6 (2) and 79.5 (1)°, respectively]. The nitrile group bond vector forms an angle of 59.4 (1)° with the dihydroquinoline plane. Both H atoms of the amide group participate in intermolecular hydrogen bonds which link molecules into infinite chains running along the a axis of the crystal structure.
