Reaction Steps

Lithium borohydride (20.8 g) was slowly added to a solution of methyl 4-bromo-3,5-dimethoxybenzoate (133.2 g) in tetrahydrofuran (500 mL) at room temperature, and the mixture was stirred for 3 hours while heating to reflux. The reaction mixture was cooled to room temperature, ice water (1.5 L) was added, and then ethyl acetate (1.2 L) was further added for extraction. The obtained organic extract was washed with brine and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure to afford the title compound (118.8 g) as a white solid.
