Participants

Reaction Steps

A solution of 5.0 ml (34 mmol) 2-chloro-5-nitrobenzotrifluoride in 100 ml ethanol was hydrogenated at atm. pressure by using Raney-Ni (1 g) as a catalyst. The reaction mixture was filtered and evaporated in vacuo. The residue was dissolved in ethanol and the solution was acidified with concentrated hydrochloric acid. The precipitate was filtered off to give 6.3 g (81%) of 4-chloro-3-trifluoromethylaniline, hydrochloride. M.p.>200° C.
