title: Ethyl 2-(6-amino-5-cyano-3,4-dimethyl-2H,4H-pyrano[2,3-c]pyrazol-4-yl)acetate.
abstract: In he title compound, C(13)H(16)N(4)O(3), 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, inter-molecular N-H⋯N and N-H⋯O inter-actions lead to a linear chain motif.
