Procedure
A solution of 64 percent aqueous hydrazine (75.6 g., 1.5 moles) is added dropwise to a warm (50° C.) stirred mixture of 2-nitro-5-ethylthiobenzotrifluoride (168.3 g, 0.67 mole) and 5 percent palladium on carbon catalyst (14.5 g) in 95 percent ethanol (1200 ml). After all of the hydrazine has been added, the reaction mixture is heated under reflux overnight. Thin layer chromatography indicates all of the nitro compound is reduced. The reaction mixture is then filtered and concentrated under reduced pressure. The residual golden colored liquid is taken up in methylene chloride and washed with water. The methylene chloride is removed by evaporation leaving the product,
