چکیده
In the title compound, C(15)H(20)N(2)O(3), prepared from the reaction of 2-amino-4,5-dimeth-oxy-benzonitrile and cyclo-hexa-none, the six-membered diaza ring assumes an envelope conformation. In the crystal, inversion dimers are formed by pairs of N-H⋯O hydrogen bonds. Futher N-H⋯O hydrogen bonds link the dimers into a two-dimensional structure parallel to (001).
