Abstract

In the title compound, C17H18N4O4, the dihedral angle between the benzene ring and 2,4-di-hydro-pyrano[2,3-c]pyrazole ring system is 89.41 (7)°. The pyran moiety adopts a strongly flattened boat conformation. In the crystal, mol-ecules are linked by N-H⋯N, N-H⋯O, C-H⋯N and C-H⋯O hydrogen bonds into an infinite two-dimensional network parallel to (110). There are π-π inter-actions between the pyrazole rings in neighbouring layers [centroid-centroid distance = 3.621 (1) Å].

Keywords: crystal structure.
