1-Nitro-4-(2,2,2-trifluoro-1,1-dimethyl-ethoxy)-benzene (4.9 g) in methanol (30 ml) was hydrogenated over Pd/C (10%, 500 mg) at RT and atmospheric for 12 h. The catalyst was filtered off and the solvent removed in vacuo to give the desired 4-(2,2,2-trifluoro-1,1-dimethyl-ethoxy)-phenylamine (4.2 g) as a brown oil that was used without further purification in the next step.
