The 1,4-dihydro-pyridine ring is approximately perpendicular to the benzene ring [dihedral angle = 88.3 (1)°]. The mol-ecular conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond. In the crystal, mol-ecules are linked by N-H⋯O inter-actions into a C(8) chain along [100].Acta crystallographica.
