Reaction Steps

To a stirred solution of ethyl 4-methyl-2-(4-nitro-3-(2,2,2-trifluoroethoxy)phenyl)pentanoate (1.5 g), in dry MeOH (100 mL), Pd(OH)2 (500 mg) was added and the mixture reduced under an atmosphere of H2 for 6 h at room temperature. The mixture was filtered through a pad of Celite™ washing with MeOH. The combined filtrates were concentrated under reduced pressure to give ethyl 2-(4-amino-3-(2,2,2-trifluoroethoxy)phenyl)-4-methylpentanoate (1.2 g) as a thick liquid.
