A catalytic amount of 10% palladium/activated carbon was added to a solution of 3-(4-methoxyphenyl)acrylic acid (15 g, 14.7 mmol) in tetrahydrofuran (50 mL). The hydrogenation reaction was carried out at room temperature with continuous stirring for 5 hours. Upon completion of the reaction, the mixture was filtered to remove the catalyst and the filtrate was concentrated in vacuum to give the white solid product 3-(4-methoxyphenyl)propionic acid in 95.2% yield with a melting point of 102-103 °C.
