Procedure

2-Dimethylamino-4,5,6,7-tetrabromobenzimidazole (0.48 g, 1 mmol) was dissolved by heating in EtOH (80 ml) and to this solution hydrochloric acid (36% H2O sol., 5 ml) was added. Almost immediately the microcrystalline solid begins to separate. The mixture was kept in 4° C. overnight and hydrochloride (350 mg, 68%) was separated as small needles. M.p. >330° C. (decomp.).
