Procedure

5 g (43 mmol) of 3-fluoro-cinnamic acid, 5.35 g (43 mmol) of 5-norbornene-2-methanol, and 0.21 g (0.02 eq.) of zirconium(IV) acetate hydroxide were added to 50 ml of toluene and stirred. The mixture was heated to 145° C. under N2 atmosphere and azeotropically refluxed for 24 hours. After the reaction, the mixture cooled down to room temperature and was added with 100 volume % of ethyl acetate. The resulting product was extracted by 1M HCl and washed again with water. The organic layer was dried with Na2SO4 and the solvent was evaporated out to give a highly viscous material. (Yield: 54%, Purity (GC): 73%)
