실험 절차

N,N-Dimethylsulphamide (73 mg, 0.59 mmoles), 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (31 mg, 0.162 mmoles) and dimethyl-pyridin-4-yl-amine (1 mg) were added to a stirred solution of 4-(4′-methoxy-biphenyl-4-yloxymethyl)-5-methyl-furan-2-carboxylic acid (4) (50 mg, 0.148 mmoles) in dichloromethane (20 ml). The mixture was stirred under an argon atmosphere for 18 hours. After evaporation of the solvent, the residue was partitioned between dichloromethane and water. The aqueous phase was separated and extracted with dichloromethane. The combined extracts were washed with 1M aqueous hydrochloric acid, saturated aqueous sodium bicarbonate, brine and dried (MgSO4). Evaporation of the solvent afforded the crude product, which was purified by HPLC (gradient: 30% acetonitrile/70% water containing 0.1% trifluoroacetic acid to 98% acetonitrile/2% water at a rate of 1%/min) to afford compound 122 (23.5 mg) as a white solid. LC/MS System C: Rt=3.67 mins, m/z (ES−)=443 ((M−H) for C22H24N2O6S).
