Following the general procedure of Wolf, Christian et al. (SynLett 2003 12, 1801-1804), to a solution of 6-bromo-4-chloroquinoline (30 g, 0.124 mol) in anhydrous THF (500 mL) was added 2 M HCl in diethylether (74 mL, 0.148 mol). A white precipitate formed immediately. After stirring for 30 min, the suspension was concentrated in vacuo and dried under vacuum to provide 6-bromo-4-chloroquinoline hydrochloride as an off-white solid (34.6 g, quantitative yield).
