Using the method of Example 133, 1-isobutyl-1H-imidazo[4,5-c]quinolin-5-oxide (from Example 74) was reacted with acetic anhydride to provide 4-hydroxy-1-isobutyl-1H-imidazo[4,5-c]quinoline, m.p. >300° C. after recrystallization from N,N-dimethylformamide. Analysis: Calculated for C14H15N3O: %C, 69.7; %H, 6.3; %N, 17.4; Found: %C, 69.8; %H, 6.4: %N, 17.6.
