Abstract: In the title compound, C 22H 25N 3O 4, the dihydro-pyridine ring adopts a flattened boat conformation. The pyrazole ring makes a dihedral angle of 29.04 (5) with the benzene ring. The mol-ecular structure is stabilized by an intra-molecular C - H?O hydrogen bond which generates an S(9) ring motif. In the crystal, molecules are linked via N - H?O and C - H?N hydrogen bonds into a two-dimensional network parallel to the ab plane. The crystal structure is further consolidated by weak C - H?? inter-actions.
