1-Isobutyl-N,N-dimethyl-1H-imidazo[4,5-c]quinolin-4-amine.

In the title compound, C(16)H(20)N(4), the 1H-imidazo[4,5-c]quinoline ring system is approximately planar, with a maximum deviation of 0.0719 (15) Å. An intra-molecular C-H⋯N hydrogen bond contributes to the stabilization of the mol-ecule, forming an S(6) ring motif. In the crystal, the mol-ecules are stacked along the b axis through weak aromatic π-π inter-actions between benzene and imidazole and benzene and pyridine rings [centroid-centroid distances = 3.6055 (10) and 3.5342 (10) Å, respectively].
