Reaction Steps

To a cooled and stirred solution of methyl 4-bromo-3-(trifluoromethoxy)benzoate (28.2, 2.60 g, 8.70 mmol) in THF (20 mL) under nitrogen, was added DIBAL-H (19.2 mL, 1.0 M in toluene) at −78° C. The reaction mixture was stirred at 0° C. for 10 minutes and 5.0 mL of water was added. The resulting mixture was stirred at room temperature for 2 hours. The solid was then filtered off. EtOAc (100 mL) was added, and the mixture was washed with brine (20 mL) and dried with Na2SO4. The solvent was removed to give 28.3. 1H NMR (CDCl3) δ 1.91 (s, 1H), 4.71 (s, 2 H), 7.18 (d, J=6.3 Hz, 1H), 7.36 (s, 1H), 7.63 (d, J=6.3 Hz, 1 H).
