Reaction Steps
To a solution of methyl 4-bromo-3,5-dimethoxybenzoate (133.2 g) in tetrahydrofuran (500 mL) was added lithium borohydride (20.8 g) slowly at room temperature, and the mixture was further stirred for 3 hours under reflux with heating. The reaction mixture was cooled down to room temperature, and ice water (1.5 L) and ethyl acetate (1.2 L) were added, and extraction with ethyl acetate was performed. The resultant organic layer was washed with saturated saline, and dried over anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure, to obtain 118.8 g of a title compound as white solid.
