Reaction Steps

To a stirred solution of benzoic acid (61 mg) in a mixture of tetrahydrofuran (10 mL) and N,N-dimethylformamide (5 mL) was added 4-(N,N-dimethylamino)pyridine (3.0 mg), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (118 mg) and 4-(biphenyl-4-yloxymethyl)-5-methyl-furan-2-sulfonic acid amide (45) (206 mg). After 16 hours at room temperature the reaction mixture was concentrated in-vacuo, then partitioned between 0.1M hydrochloric acid (30 mL) and ethyl acetate (3×30 mL). The combined organic extracts were washed with brine (25 mL), dried (MgSO4) and concentrated in vacuo. The crude product was purified by HPLC to give compound 46 as light beige solid (17 mg). LC/MS System C: Rt=5.69 mins, m/z (ES−)=446 (M− for C25H21NO5S).
