実験手順
Aqueous sodium hydroxide (30 g of 50%) was added to a suspension of 2-methyl-[(4-nitro-5-tetrazolo[1,5-a]quinolinyl)amino]-2-propanol (34.0 g, 0.1125 mole, Example 3) in water (500 mL). The mixture was heated on a steam bath and the solid dissolved rapidly. The solution was heated for about 30 minutes and then upon stirring a solid begin to precipitate. The mixture was made acidic with 6N hydrochloric acid. The resulting solid was isolated by filtration; washed in succession with water, ethanol and ether; then dried under vacuum at 100° C. to provide 23.2 g of crude product as a pale yellow/green solid. A sample (3.2 g) was recrystallized initially from methanol/dichloromethane and then from toluene to provide 4-nitrotetrazolo[1,5-a]quinolin-5-ol. Analysis: Calculated for C9H5H5O3: %C, 46.76; %H, 2.18; %N, 30.29; Found: %C, 46.85; %H, 2.23; %N, 29.91.
