Abstract
In the crystal structure of the title compound, C19H20N2O3·C3H6O, molecules are linked into inversion dimers with an R22(12) motif by pairs of N—H...N hydrogen bonds. These dimers are further connected into chains running along the a axis by N—H...O hydrogen bonds. C—H...N and C—H...π interactions also feature in the packing. The cyclohexene ring adopts nearly an envelope conformation [puckering parameters are QT = 0.456 (2) Å, θ = 54.6 (3)° and ϕ = 225.2 (3)°].
