Reaction Steps

To a solution of methyl 3-bromo-4-hydroxy-benzoate (1.00 g, 4.33 mmol, 1.00 eq) in toluene (15.00 mL) were added vinyl acetate (745.54 mg, 8.66 mmol, 2.00 eq), Chloro(1,5-cyclooctadiene)iridium(I) dimer (29.08 mg, 43.30 umol, 0.01 eq) and Na2CO3 (229.47 mg, 2.17 mmol, 0.50 eq). The mixture was stirred at 100° C. for 16 hr under N2 protection. TLC detected the reaction was complete, the solvent was evaporated, the residue was purified by chromatography (silica gel, eluting with PE:EA=10:1) to afford product methyl 3-bromo-4-vinyloxy-benzoate (730.00 mg, 2.84 mmol, 65.58% yield) as colorless oil. 1H NMR (400 MHz, CDCl3) δ 8.29 (d, J=1.76 Hz, 1H), 7.99 (dd, J=8.53, 2.01 Hz, 1H), 7.06 (d, J=8.53 Hz, 1H), 6.65 (dd, J=13.80, 6.02 Hz, 1H), 4.98 (dd, J=13.80, 2.01 Hz, 1H), 4.70 (dd, J=5.90, 1.88 Hz, 1H), 3.93 (s, 3H).
