title: Ethyl 2-methyl-4-phenyl-quinoline-3-carboxyl-ate.
abstract: In the mol-ecule of the title compound, C(19)H(17)NO(2), the quinoline ring system is planar [maximum deviation 0.021 (3) Å] and oriented with respect to the phenyl ring at a dihedral angle of 80.44 (4)°. Intra-molecular C-H⋯O inter-actions result in the formation of five- and six-membered rings having planar and envelope conformations, respectively. In the crystal structure, inter-molecular C-H⋯O inter-actions link the mol-ecules into centrosymmetric dimers forming R(2) (2)(12) ring motifs. π-π contacts between the rings of the quinoline system [centroid-to-centroid distance = 3.812 (1) Å] may further stabilize the structure. Two weak C-H⋯π inter-actions are also found.
