Reaction Steps

8.6 g of 6-chloro-2-mercapto-4-methylbenzothiazole are reacted with 4.4 g of maleic anhydride in 70% H2SO4 at 47°-50° as described in Example 1. The crude product is purified by reprecipitation from NaHCO3 solution. 6-Chloro-4-methylbenzothiazol-2-ylthiosuccinic acid of melting point 168°-171°, with decomposition, is obtained.
