5.3 g of 2,4'-dichloro-3'-sulfamoylacetophenone and 3.2 g of ground 1,3-dipropylthio urea were heated in 45 ml of methanol for 5 minutes to 50° C and stirred for another 30 minutes at room temperature. After pouring the reaction mixture into 120 ml of diethyl ether the end product was obtained as a visquous mass which crystallized under mild heating rapidly with ether. Colorless solid body: melting point: 175° C (decomposition).
