Abstract: In the title compound, C₁₃H₁₈N₂O₃, the two H atoms of the NH₂ group are engaged in hydrogen bonding with the N atom of the cyano group and with one O atom of the ethoxycarbonyl group, building a chain parallel to the [100] direction. The N-HN hydrogen bonds assemble the molecules around inversion centres, forming dimers with an R₂²(12) graph-set motif.
