Versuchsvorschrift

m-Aminobenzotrifluoride (48.34 g: 0.3 mole) was cooled and treated with concentrated hydrochloric acid (137 ml) added dropwise. The paste was stirred at 0° and a solution of sodium nitrite (19.1 g) in water (137 ml) was added at 0°-5° with stirring. An almost clear solution was obtained. Then a solution of stannous chloride dihydrate (191.3 g) in concentrated hydrochloric acid (137 ml) was added dropwise with stirring at 0°-10°.
