Reaction Steps

2,3,4-Trifluoroaniline (25 g) was added to concentrated hydrochloric acid (125 ml), and an aqueous solution (20 ml) of sodium nitrite (12.9 g) was added dropwise under ice-cooling. A solution of tin (II) chloride (114.6 g) in concentrated hydrochloric acid (50 ml) was separately prepared and it was added dropwise to the reaction solution. The precipitated solid was collected by filtration, added to an aqueous solution of sodium hydroxide and the aqueous solution was extracted with toluene to give 2,3,4-trifluorophenylhydrazine (9.3 g).
