Reaktionsschritte

3-Hydroxy-4-methoxycinnamic acid (15.0 g, 77.2 mmo) and 10% palladium carbon in the water content of 50% (2.26 g) were added to a mixed solvent (330 ml) of methanol and water (mixing ratio of 10:1 v/v), and the mixture was stirred under hydrogen atmosphere of normal pressure (0.1 MPa) at 50° C. for 5 hours for reaction. The reaction solution was filtrated to remove the catalyst, and the filtrate was concentrated under reduced pressure to solidification to obtain 3-(3-hydroxy-4-methoxyphenyl) propionic acid (15.1 g, 76.7 mmol, yield: 99%).
