Reaktionsschritte

A mixture of 1-(2,2,2-trifluoroethoxy)-2-nitrobenzene (15 g, 68 mmol), platinum oxide hydrate (100 mg) and absolute ethanol (80 mL) was hydrogenated 18 hours with stirring at 25° C. and 15 psi of pressure. The reaction mixture then was filtered and concentrated. The residue was purified by column chromatography on silica gel eluting with hexane/ethyl acetate (9:1) to give 2-(2,2,2-trifluoroethoxy)aniline (10.4 g, 54.5 mol), m.p. 49°-50° C.
