A solution of carbon disulphide (17.5 cc) in anhydrous acetonitrile (19.5 cc) is added, at 25° C., to a solution of 2-amino-6-ethylpyridine (27.0 g) in anhydrous triethylamine (60 cc). After stirring for 20 hours at 20° C., anhydrous diethyl ether(250 cc) is added. After cooling for 1 hour at 2° C., the resulting crystals are filtered off, washed three times with anhydrous diethyl ether (total 240 cc) and dried under reduced pressure (20 mm Hg) at 20° C. Triethylammonium 6-ethylpyrid-2-yldithiocarbamate (42.0 g), melting at 75° C., is thus obtained.
