3-(4-Methoxyphenyl)-2-phenylprop-2-enoic acid → 3-(4-Methoxyphenyl)-2-phenylpropionic acid

Participants

Reaction Steps

13 g of 3-(4-methoxyphenyl)-2-phenylacrylic acid was dissolved to 600 ml of ethyl acetate and 2.6 g of 10% palladium on charcoal was added under inert atmosphere. Starting material was hydrogenated at room temperature to give quantitative yield of 3-(4-methoxyphenyl)-2-phenylpropionic acid. 1H-NMR (400 MHz, d6-DMSO): 12.3 (bs, 1H), 7.32-7.20 (m, 5H), 7.1-7.0 (m, 2H), 6.8-6.7 (m, 2H), 3.79 (dd, 1H, J 6.9, 8.7 Hz), 3.70 (s, 3H), 3.22 (dd, 1H, J 8.7, 13.7 Hz), 2.87 (dd, 1H, J 6.9, 13.7 Hz).
