실험 절차
Piperidine (0.22 ml) is added to a solution of ethyl 2,3-dibromo-3-(3'-methoxyphenyl)-4-fluorobutyrate (0.80 g) in ether (10 ml). The reaction mixture is stirred at room temperature for 3 hours and water is added. Ether extraction gives essentially pure ethyl 2-bromo-3-(3'-methoxyphenyl)-4-fluoro-2-butenoate (0.65 g).
