실험 절차
Pentafluorophenyl trifluoroacetate (1.47 ml; 8.6 mmol) was added to a solution of 5-[3-(imidazol-1-yl)prop-1-en-1-yl]-2-(4-fluorophenethyl)benzoic acid (2.5 g, 7.14 mmol) and pyridine (0.7 ml; 8.6 mmol) in DMF (7 ml). After stirring at ambient temperature overnight, the mixture was evaporated to dryness and the residue extracted with ethyl acetate, washed with saturated sodium hydrogen carbonate and saturated sodium chloride. After evaporation the reaction mixture was purified by flash chromatography eluting with dichloromethane/ethanol (99/1) to give E isomer pentafluorophenyl 5-[(E)-3-(imidazol-1-yl)prop-1-en-1-yl]-2-(4-fluorophenethyl)benzoate and Z isomer pentafluorophenyl 5-[(Z)-3-(imidazol-1-yl)prop-1-en-1-yl]-2-(4-fluorophenethyl)benzoate. Yield: 68%
