실험 절차

A solution of 3′-fluoro-2′,6′-dimethyl-4′-[3-(methylsulfonyl)propoxy]biphenyl-3-carbaldehyde (2.77 g, 8.00 mmol) in a mixed solvent of methanol (10 mL) and tetrahydrofuran (20 mL) was ice-cooled, sodium borohydride (90%, 0.336 g, 8.00 mmol) was added, and the mixture was stirred for 8 hr under nitrogen atmosphere. The reaction mixture was treated with diluted hydrochloric acid, and extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate:hexane=40:60-80:20), and the obtained crystals were recrystallized from heptane-ethyl acetate to give the title compound (2.75 g, yield 94%) as colorless crystals.
