Participants

Reaction Steps

N5-(2-Methylpropyl)tetrazolo[1,5-a]quinoline-4,5-diamine (0.2 g, 0.78 mmole, Example 16) was combined with diethoxymethyl acetate (2 mL) and heated on a steam bath for 3 hours. Water (10 mL) and 10% sodium hdyroxide (2 mL) were added and the reaction mixture was heated on a steam bath for 1 hour. A solid was isolated by filtration then recrystallized from methanol/ethyl acetate to provide 0.16 g of 6-(2-methylpropyl)-6H-imidazo[4,5-c]tetrazolo[1,5-a]quinoline as a white crystalline solid, m.p. 210-212° C. Analysis: Calculated for C14H14N6; %C, 63.14; %H, 5.30; %N, 31.56; Found: %C, 63.12; %H, 5.32; %N, 31.61.
