실험 절차

Triphenyl phosphine (50 mg, 0.191 mmol) was added to a solution of {4-[(2R,3R)-1-(4-fluoro-phenyl)-3-(3-nitro-pyridin-2-yldisulfanyl)-4-oxo-azetidin-2-yl]-phenoxy}-acetic acid tert-butyl ester (100 mg, 0.179 mmol) in acetone/water (3 mL/0.5 mL) at room temperature. The mixture was stirred for 15 min. The solvent was removed under reduced pressure and the residue was dissolved in DCM (3 mL). Et3N (75 μL, 0.534 mmol) and 2-bromo-1-(2,3-dihydro-benzofuran-6-yl)-ethanone (91 mg, 0.377 mmol) were added and the solution was stirred at room temperature for 16 h. The solvent was removed under reduced pressure and the residue was purified by preparative HPLC using a gradient of 40-80% MeCN in a 0.1M ammonium acetate buffer as eluent. The pure fractions were pooled and most of the MeCN was removed under reduced pressure. The residue was extracted with EtOAc and the organic layer was washed with brine, dried over MgSO4 and concentrated. The title compound was obtained.
