Procedure

Concentrated hydrochloric acid (18.5 mmol) was added to a solution of 2-ethylthiazolo[4,5-c]quinolin-4-amine (4.25 g) in warm isopropanol. The reaction mixture was heated at reflux to reduce the volume and remove the water. The reaction mixture was cooled to ambient temperature. The precipitate was isolated by filtration and then dried to provide 2-ethylthiazolo[4,5-c]quinolin-4-amine hydrochloride as a solid, m.p. 268-270° C. Analysis: Calculated for C12H11N3S HCl: %C, 54.23; %H, 4.55; %N, 15.81; Found: %C, 54.25; %H, 4.63; %N, 15.71.
