Procedure

At 20° C., 57 g (0.173 mol) of 2-trifluoromethoxy4,5-dichloro-benzene sulphochloride are metered to 200 ml of a 25% strength ammonia solution. After stirring of the mixture has continued for 1 hour, the solid is filtered off with suction and subsequently washed with water and dried. Yield 44 g (=83% of theory); melting point 181 to 185° C.
