A solution of carbon disulphide (20 cc) in anhydrous acetonitrile (23 cc) is added, at 20° C., to a solution of 2-amino-6-propylpyridine (34.0 g) in anhydrous triethylamine (69 cc). After stirring of the mixture for 20 hours at 20° C., anhydrous diethyl ether (800 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 300 cc) and dried under reduced pressure (20 mm Hg) at 20° C. Triethylammonium 6-propylpyrid-2-yldithiocarbamate (50.3 g), melting at about 98° C., is obtained.
