Procedure

A stirred solution of 4-(biphenyl-4-yloxymethyl)-5-methyl-furan-2-carboxylic acid (18) (50 mg, 0.162 mmoles), 2-methyl-benzenesulphonamide (42 mg, 0.243 mmoles) and 4-(N,N-dimethylamino)-pyridine (2.5 mg) in a mixture of tetrahydrofuran (8 ml) and acetonitrile (2 ml) was treated with 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (38 mg, 0.194 mmoles). The mixture was stirred at room temperature for 16 hours under an argon atmosphere. The reaction mixture was concentrated in vacuo and the residue was purified by HPLC to afford compound 60 (20 mg) as a white solid. LC/MS System D; Rt=11.09 mins, m/z (ES+)=462 (M+H for C26H23NO5S).
