Reaction Steps

6.1 g of 2-bromo-4'-chloro-3'-sulfamoylacetophenone were heated with 2.4 g of 1-methyl-3-isopropylthiourea in 50 ml of acetone for 10 minutes to 40° C, the separating oil was triturated to form crystals and the crystalline suspension was stirred for 1 hour at room temperature. Colorless solid body: melting point: 195° C (decomposition).
