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—H⋯N hydrogen bonds assemble the molecules around inversion centres, forming dimers with an R 2 2(12) graph-set motif.
