실험 절차
A solution of 3-fluoro-4-aminohydrocinnamic acid in 100 ml. of absolute ethanol containing 16 ml. of boron trifluoride etherate is heated to reflux for 48 hours. The solution is then cooled, poured into 5% aqueous sodium carbonate and extracted with methylene chloride. Evaporation of the organic extracts yields ethyl 3-fluoro-4-aminohydrocinnamate.
