To a solution of 6.76 g. (0.03 mole) of 2-benzyl-5-chloro-4-isothiazolin-3-one in 25 ml of ethanol was added a solution of 5.37 g. (0.03 mole) of N,N-dimethyldithiocarbamic acid sodium salt dihydrate in 30 ml of ethanol followed by 0.1 g. of sodium iodide. A yellow solid separated spontaneously. The mixture was stirred at room temperature for 3 hours, then cooled and filtered. The solid was triturated with 50 ml of water and recrystallized from 250 ml of boiling EtOH to give 5.6 g. (60% yield) of the named product, mp 184°-186°.
