実験手順

To a solution of 3′-fluoro-4′-hydroxy-2′,6′-dimethylbiphenyl-3-carbaldehyde (2.44 g, 10.0 mmol) and 3-(methylsulfonyl)propyl 4-methylbenzenesulfonate (3.51 g, 12.0 mmol) in N,N-dimethylformamide (20 mL) was added potassium carbonate (1.80 g, 13.0 mmol), and the mixture was stirred at 90° C. for 24 hr under nitrogen atmosphere. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed successively with 1 M aqueous sodium hydroxide solution and 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 (3.45 g, yield 95%) as colorless crystals.
