title: Ethyl 6-amino-5-cyano-4-isopropyl-2-methyl-4H-pyran-3-carboxyl-ate.
abstract: In the title compound, C(13)H(18)N(2)O(3), the two H atoms of the NH(2) group are engaged in hydrogen bonding with the N atom of the cyano group and with one O atom of the ethoxy-carbonyl group, building a chain parallel to the [100] direction. The N-H⋯N hydrogen bonds assemble the mol-ecules around inversion centres, forming dimers with an R(2) (2)(12) graph-set motif.
