実験手順

20 g (0.113 mole) of 3-trifluoromethyl-phenylhydrazine were dissolved in 50 ml of methanol with addition of 5 ml of acetic acid; 16 g (0.115 mole) of sulfinylaniline were added dropwise at a temperature of 22°C. The product crystallized out while the temperature rose to about 30°C. After filtration and drying, 16 g of N-sulfinyl-N-' -(3-trifluoromethylphenyl)-hydrazine of melting point 100°C were obtained. The yield was 64% of theory.
