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.Article
