Reaktionsschritte
3-(4-Benzyloxyphenyl)-2-ethoxyacrylic acid ethyl ester (described in Example 1a) (0.5 g; 1.5 mole) was hydrogenated at atmospheric pressure using rhodium on charcoal as catalyst (5%, 50 mg) in methanol (20 ml). The crude product was purified by chromatography using heptane:ethyl acetate (5:1) as eluent to give 50 mg (yield 10%) of 3-(4-benzyloxyphenyl)-2-ethoxypropanoic acid ethyl ester.
