4,4-Dimethyl-3-oxopentyltrimethylammonium iodide (6.0 g) is added, at 20° C., to a suspension of triethylammonium 5-chloropyrid-2-yldithiocarbamate (6.1 g) in anhydrous acetonitrile (25 cc). The reaction is allowed to proceed for 6 hours at 20° C. Distilled water (25 cc) is added. The crystals which appear are filtered off, washed three times with distilled water (total 30 cc) and dried in air at 20° C. The product obtained (5.1 g; m.p.=110° C.) is recrystallised from acetonitrile (15 cc). 4,4-Dimethyl-3-oxopentyl 5-chloropyrid-2-yldithiocarbamate (3.8 g), which melts at 111° C., is obtained.
