Reaction Steps

3.34 g of 3-[2-[(4-bromophenyl)-(4-fluorophenylamino)methyl]-5-(tert-butyl-dimethylsilanyloxy)-5-(4-fluorophenyl)pentanoyl]-4-phenyloxazolidin-2-one are suspended in 70 ml of tert-butyl methyl ether. 3.8 ml of bis(trimethylsilyl)acetamide and 144 mg of tributylammonium fluoride trihydrate are then added. The reaction mixture is stirred at room temperature overnight, and 0.7 ml of glacial acetic acid are then added. The reaction mixture is concentrated using a rotary evaporator and the residue is purified by column chromatography (SiO2; ethyl acetate/heptane 1:4). The product is obtained as a clear oil. C30H34BrF2NO2Si (586) MS (ESI): M+−131
