Reaction Steps

To a stirred solution of 2-(4-nitrophenyl)propionic acid (2.05 g) in THF (20 mL) and EtOH (20 mL) was slowly added 10% Pd/C (0.21 g) at room temperature. After hydrogenated for 2 h with H2 balloon, the reaction mixture was filtered through celite pad and washed with EtOH. The filtrate was concentrated in vacuo to afford the product as pale brown solid. (1.75 g, quantitative)
