Acetic Acid → HCID 18424794, compound

Participants

Reaction Steps

2,3-Dimethoxycinnamic acid (50 g, 0.24 m) was suspended in a mixture of 120 ml of ethanol and 40 ml of glacial acetic acid, then treated with 0.8 g of 10% palladium-on-charcoal. The mixture was warmed on a steam bath before putting on the Paar shaker. Hydrogenation was continued until the uptake of hydrogen stopped (45 minutes). The catalyst was filtered off and the resulting filtrate was evaporated to dryness. The resulting residue solidified on standing. A quantitative yield of the desired 2,3-dimethoxyphenylpropionic acid was isolated.
