Reaction Steps
27 g of 3-[5-(4-fluorophenyl)-5-hydroxypentanoyl]-4-phenyloxazolidin-2-one, 13.6 g of tert-butyldimethylsilyl chloride and 10.2 g of imidazole are dissolved in 36 ml of dimethylformamide, and the mixture is stirred at 60° C. for 90 min. After the reaction has ended, the mixture is dissolved in ethyl acetate and extracted twice with waiter. The organic phase is dried over magnesium sulfate, filtered and concentrated under reduced pressure. This gives 3-[5-(tert-butyldimethylsilanyloxy)-5-(4-fluorophenyl) pentanoyl]-4-phenyloxazolidin-2-one of molecular weight 471.65 (C26H34FNO4Si); MS (ESI): 340.28 (MH+—HOSi(CH3)2C(CH3)3).
