Procedure
Imidazole-4-sulphonyl chloride was reacted with 4-chloro-N-methylaniline to give 4-[N-(4-chlorophenyl)-N-methylsulphamoyl]imidazole, m.p. 217°-9°. This was then treated with dimethylsulphamoyl chloride in a similar manner to that described in Example 1, to give 1-dimethylsulphamoyl-4-[N-(4-chlorophenyl)-N-methylsulphamoyl]imidazole, m.p. 131.5°-132°.
