The title compound, C(17)H(18)N(6)O(2)center dot 0.5CH(3)OH, exists in the double keto form and adopts a highly puckered geometry, stabilized by intramolecular N-H center dot center dot center dot O and N-H center dot center dot center dot N hydrogen bonds. Intermolecular N-H center dot center dot center dot N hydrogen bonds and pi-pi stacking interactions [centroid-centroid separation = 3.654 ( 1) angstrom] assemble the molecules into chains running in the [111] direction. The methanol solvent molecule is disordered over two sites related by inversion and forms a bifurcated O H center dot center dot center dot(N, O) hydrogen bond.
