N-(1,1-dimethylethyl)-4-nitrotetrazolo[1,5-a]quinolin-5-amine (4.2 g, Example 18), ethanol (100 mL) and Pt/C (0.5 g) were placed in a Paar apparatus. The mixture was hydrogenated. The reaction mixture was filtered to remove catalyst then concentrated to dryness under vacuum. The residue was recrystallized from ethyl acetateldichloromethane to provide N5-(1,1-dimethylethyl)tetrazolo[1,5-a]quinoline-4,5-diamine as a pale blue crystalline solid.
