ABSTRACT
In the title compound, C22H20N2O2, both six-membered rings of the fused heterocyclic system display envelope conformations; the two carbon atoms bearing the methyl groups and the naphthyl substituent both lie outside the planes of the other atoms of each ring. In the crystal, the amino group forms hydrogen bonds of the types N-Hâ¯O=C and N-Hâ¯N≡C, leading to the formation of a double layer structure propagating parallel to the bc plane. Weak C-Hâ¯O and C-Hâ¯π inter-actions may reinforce the layers.
