Reaktionsschritte

A solution of (3-nitrophenoxy)-acetic acid ethyl ester (500 mg, 2.22 mmol) in methanol (20 ml) was hydrogenated over 10% Pd—C (50 mg) at atmospheric pressure until no further gas uptake was observed. The reaction mixture was then filtered over celite and concentrated to yield a residue which was purified over neutral alumina using ethyl acetate-hexane to give (3-amino-phenoxy)-acetic acid ethyl ester (330 mg, 77%) as oil.
