The general procedure for the synthesis of 4-amino-6-(1,2,2-trichlorovinyl)benzene-1,3-disulfonamide from the compound (CAS: 60285-85-0) is as follows: 100 mL of ethanol and 350 mL of water were mixed and stirred well, then 20 g of ammonia and 2 g of activated carbon were added. The mixture was heated to reflux for 1 hour, followed by thermal filtration. The residue was washed with 50 mL of ethanol and 100 kg of water. The filtrate was slowly cooled to 10 °C, filtered and dried to give 16.5 g of chlorosulfuron in 82.5% yield.
