Procedure

120 g of dimethylamine were introduced into a solution of 620 g of 3-chloro-4-methylsulfonyloxyphenylisocyanate (alternative name: methanesulfonic acid 2-chloro-4-isocyanatophenyl ester) in 2.5 liters of chlorobenzene at a temperature of 5°-22°C, whilst cooling. The crystals which thereupon formed were filtered off and dried. Yield: 714 g of N-(3-chloro-4-methylsulfonyloxyphenyl)-N',N'-dimethylurea, of melting point 130°-132°C.
