Reaction Steps

Dithio-(3',4'-dichloro)-diisobutyranilide, 12.8 g. (0.0234 mole), was slurried in 250 ml. of ethylene dichloride, and a solution of 9.5 g. (0.0702 mole) of sulfuryl chloride in 25 ml. of ethylene dichloride was added dropwise at 25°-30° C. over one hour. The slurry was stirred overnight to insure completion of the reaction and then filtered to give 8.6 g. of gray 2-(3,4-dichlorophenyl)-4-methyl-3-isothiazolone, m.p. 160°-161° C. The product was crystallized from ethyl acetate to give a m.p. of 161°-163° C.
