Reaction Steps

3-{5-(4-Fluorophenyl)-2-[(4-fluorophenylamino)-(4-trimethylsilanyloxy-phenyl)methyl]-5-trimethylsilanyloxypentanoyl}-4-phenyloxazolidin-2-one (10 mg) is suspended in MTB ether (1 ml) under argon while cooling in ice. N,O-Bistrimethylsilylacteamide (20.75 μl) is added, followed by tetrabutylphosphonium chloride (4.2 mg) and silver(I) oxide (3.2 mg). The mixture is stirred at room temperature. A reaction to give 1-(4-fluorophenyl)-3-[3-(4-fluorophenyl)-3-trimethylsilanyloxypropyl]-4-(4-trimethylsilanyloxyphenyl)azetidin-2-one is found by means of thin-layer chromatography and LC/MS comparison (M+H,-TMS,-HOTMS: 392).
