115.5 g of 2-phenylbenzenesulfonamide were dissolved in 500 ml of dimethylformamide, and 38 g of carbon disulfide and 28 g of potassium hydroxide were added to the resulting solution. The mixture was stirred at room temperature for 7 hours. Potassium hydroxide (28 g) was added to the reaction mixture, and the mixture was stirred at room temperature for 2 hours. Then, 400 ml of ethyl acetate were added dropwise to precipitate pale yellow crystals. The crystals were filtered, and washed with ethyl acetate to give 160 g of potassium N-(2-biphenylylsulfonyl)carbonimidodithioate represented by the following formula: ##STR25##
