Procedimiento

13.3 g of AlCl3 are dissolved in 100 ml of diethyl ether at 0° to 5°. 3.4 g of 2-mercaptobenzothiazole and 2.6 g of itaconic acid are then added. After the mixture has been stirred at 20°-25° for 24 hours, the ether solution is poured off and the residue is stirred with 100 ml of water and 100 ml of ethyl acetate. The organic phase is separated off, dried and evaporated. 3 g of 3-(benzothiazol-2-ylthio)-propane-1,2-dicarboxylic acid are obtained as the residue.
