Abstract
A precursor of Naproxen, 2-(6-methoxy-2-naphthyl)propenoic acid was synthesized in good yield from commercially available 6-methoxy-2-naphthaldehyde in three steps. The synthesis includes an unprecedented one-step reduction of acrylic acid ethyl ester to propenoic acid ethyl ester in high yield.
