실험 절차
To a solution of 42.2g (0.2 mole) 4-(3-chlorophenyl) urazole in 200 ml water was added a solution of 16g (0.4 mole) sodium hydroxide in 20 ml water. A mixture of 74.4g (0.4 mole) trichloromethylsulfenyl chloride and 3g of an emulsifier solution (as in example 1) in 50 ml water was added dropwise to the above basic solution while keeping the reaction mixture at 0° C. The reactants were mixed so that the reaction mixture was kept at a pH greater than 7. The precipitate that formed was filtered and the filter cake was washed with water. After drying and recrystallizing from cyclohexane there was obtained 70g (69%) 4-(3-chlorophenyl)-1,2-bis-(trichloromethylthio) urazole having a melting point of 153° C.
