Reaction Steps

To a solution of 1 g of 2-amino-1,3-benzothiazol-6-yl 2,6-dichlorobenzenesulfonate in 25 cm3 of pyridine is added 0.308 cm3 of methyl chloroformate. The solution is stirred at a temperature in the region of 20° C. overnight. After addition of 0.62 cm3 of methyl chloroformate, the mixture is stirred for 72 hours at a temperature in the region of 20° C. 50 cm3 of water are added, and the precipitate formed is filtered off by suction and then washed with three times 10 cm3 of water and dried under reduced pressure. 785 mg of 2-[(methoxycarbonyl)amino]-1,3-benzothiazol-6-yl 2,6-dichlorobenzenesulfonate are obtained in the form of a beige-coloured powder, the characteristics of which are as follows:
