실험 절차
After 3-(3-fluoro-4-methoxy-phenyl)-2-methyl-propionic acid ethyl ester (0.728 g, 3.03 mmol) obtained in Step B was dissolved in anhydrous DCM (10 mL), 1M BBr3 solution (4.5 mL, 4.5 mmol) was added thereto at −78° C., and the mixture was stirred at room temperature for 3 hours. After the termination of the reaction, the reactant was added with MeOH, concentrated under reduced pressure, and purified by column chromatography (eluent, EtOAc/Hex=1/2) to obtain the title compound (0.64 g, 99%).
