The title compound, C25H27NO4, has a flattened dihydropyridine ring. The benzene and phenyl rings are synclinal to one another, forming a dihedral angle of 49.82 (8)̊; the axis of the biphenyl rings makes an 81.05 (9)- angle to the plane of the dihydropyridine ring. In the crystal, N-H⋯O hydrogen bonds link the molecules into chain motifs running along the a-axis direction. The chains are cross-linked by C-H⋯O interactions, forming sheet motifs running slightly off the (110) plane, together with an intermolecular interaction between head-to tail biphenyl groups, thus making the whole crystal packing a three-dimensional network. Intramolecular C-H⋯O hydrogen bonds are also observed.
