実験手順
To a solution of 6-(4′-chloro-biphenyl-4-ylsulfanyl)-hexanoic acid methyl ester (900 mg, 2.6 mmol) in methanol (30 mL) and tetrahydrofuran (20 mL) was added dropwise at 0° C. a solution of sodium metaperiodate (608 mg, 2.8 mmol) in distilled water (8 mL). The mixture was heated at 60° C. for 2 hours. The solution was concentrated under reduced pressure to give an oil that was dissolved in ethyl acetate (50 mL). The organic layer was washed with saturated aqueous sodium hydrogen carbonate (50 mL), distilled water (50 mL), then with brine (50 mL). The organic layer was dried over anhydrous MgSO4, filtered and concentrated under reduced pressure to give an oil that was purified by flash chromatography (1:1 to 8:2 ethyl acetate:40-60° C. petroleum ether). The solid obtained was recrystallised from diethyl ether/40-60° C. petroleum ether to give the title compound (763 mg, 81%) as a solid, mp 64-65° C.
