In the title compound, C(20)H(21)N(3)O(4), the 1,4-dihydro-pyridine ring adopts a boat conformation. An intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif. The pyrazole ring makes dihedral angles of 87.81 (7) and 45.09 (7)° with the mean plane of the 1,4-dihydro-pyridine ring and the phenyl ring, respectively. In the crystal, mol-ecules are linked by N-H⋯N, N-H⋯O and C-H⋯O hydrogen bonds into a three-dimensional network.
