Abstract: In he title compound, C₁₃H₁₆N₄O₃, the pyrazole ring is planar (r.m.s. deviation = 0.054 Å). The pyran ring is not planar; the mean plane makes a dihedral angle of 1.9 (1)° with the pyrazole ring. In the crystal structure, intermolecular N-HN and N-HO interactions lead to a linear chain motif.
