実験手順
A stirred solution of 4-(4′-methoxy-biphenyl-4-yloxymethyl)-5-methyl-furan-2-carboxylic acid (4) (250 mg) in dichloromethane (50 mL) was treated with 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (142 mg), 4-(N,N-dimethylamino)pyridine (2 mg) and benzenesulfonamide (232 mg). After 16 hours the reaction mixture was concentrated in vacuo, the residue dissolved in ethyl acetate (200 mL) and washed successively with water (20 mL), 1.0 M hydrochloric acid (20 mL), saturated sodium hydrogen carbonate solution (20 mL), brine (20 mL), dried and concentrated in vacuo. The crude product was purified by HPLC to afford compound 5 as a white solid (30 mg). LC/MS System D: Rt=5.45 mins, m/z (ES−)=476 (M− for C26H23NO6S).
