Procedure

To a solution of 5.5 g (0.03 mole) of anhydrous cadmium chloride in 120 ml of ethanol was added a solution of 4.5 g (0.03 mole) of 5-chloro-2-methyl-3-isothiazolone in 25 ml of ethanol. A white precipitate formed immediately. The mixture was filtered and air dried to yield 10.0 g (100%) of product, m.p. >250° C.
