Versuchsvorschrift

A mixture of trans-3,5-dimethoxycinnamic acid (15.30 g, 73.48 mmol) and thionyl chloride (13.11 g, 0.11 mol) were placed in a 250 mL single-necked round-bottomed flask fitted with a magnetic stirring bar and reflux condenser. Dry methylene chloride (80.0 mL) was added to the above mixture. The resulting solution was heated to reflux for 3 hours. Then, the solvent was removed under reduced pressure. The residue was dried under vacuum overnight to give a pale-yellow solid, trans-3,5-dimethoxycinnamic acid chloride.
