Reaction Steps

To a solution of 2′,6′-diethyl-4′-hydroxybiphenyl-3-carbaldehyde (2.44 g, 9.59 mmol) and 3-(methylsulfonyl)propyl 4-methylbenzenesulfonate (3.36 g, 11.5 mmol) in N,N-dimethylformamide (20 mL) was added potassium carbonate (1.73 g, 12.5 mmol), and the mixture was stirred at 90° C. for 70 hr under nitrogen atmosphere. Water was added to the reaction mixture, and the mixture was 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=30:70-70:30) to give the title compound (2.86 g, yield 80%) as a pale-yellow oil.
