Versuchsvorschrift

The nitro intermediate (2 mmol) obtained above was dissolved in MeOH (10 mL) and hydrogenated in the presence of 10% Pd/C (50 mg) until completion as indicated by TLC or LC-MS, according to General Procedure H. The reaction mixture was then filtered to remove the catalyst. The solvent was removed in vacuuo to afford 4-(4′-fluoro-3′-trifluoromethyl-phenoxy)aniline, which was used directly for further transformation without purification.
