A mixture of 1.3 g (0.0037 mole) of 1-(2-benzoyloxyethyl)-4-chloro-1H-imidazo[4,5-c]quinoline (from Example 117) in 60 ml of methanol was saturated with about 10g of ammonia gas. The mixture was heated at 150° C. in a steel bomb for ten hours. The mixture was evaporated, and the residue was slurried in diethyl ether and filtered. The solid obtained was slurried in methanolic hydrochloric acid to provide off-white solid 1-(2-hydroxyethyl)-1H-imidazo[4,5-c]quinolin-4-amine hydrochloride hydrate, m.p. >250° C. Analysis: Calculated for C12H12N4O·HCl·1.25H2O: C, 50.2; % H, 5.4; % N, 19.5; Found: % C, 50.2; % H, 5.2; % N, 19.1.
