Procedure

A solution of sodium nitrite (2.0 g, 3 mmole) in water (5 mL) was added to a solution of 4-hydrazino-1-(2-methylpropyl)-1H-imidazo[4,5-c]quinoline (4.0 g, 15.7 mmole, Example 7) in a mixture of acetic acid (5 mL) and water (50 mL). The reaction mixture was stirred at ambient temperature for 15 minutes. A precipitate was isolated by filtration, washed with water then air dried to provide 4.1 g of crude product. This material was recrystallized from dichloromethane/ethanol to provide 3.0 g of 6-(2-methylpropyl)-6H-imidazo[4,5-c]tetrazolo[1,5-a]quinoline as a cream colored crystalline solid, m.p. 208-212° C. Analysis: Calculated for C14H14N6 : % C, 63.14; % H, 5.30; % N, 31.56; Found: % C, 62.60; % H, 5.2; % N, 31.5.
