To a stirred solution of ethyl 3-cyclopropyl-2-(3(cyclopropylmethoxy)-4-nitrophenyl)propanoate (4.0 g), in dry MeOH (100 mL), Pd(OH)2 (2 g) was added and the mixture was reduced under an atmosphere of H2 for 6 h at room temperature. The reaction mixture was filtered through a pad of Celite™ washing with MeOH. The combined filtrates were concentrated under reduced pressure to yield ethyl 2-(4-amino-3-(cyclopropylmethoxy)phenyl)-3-cyclopropylpropanoate (3.5 g) as a thick liquid.
