Reaction Steps

(S)-5-(hydroxymethyl)oxazolidin-2-one (570 mg, 4.87 mmol, as described by Danielmeier, K.; Steckhan, E. Tet. Asymmetry, 6(5), 1995, 1181) and imidazole (331 mg, 4.87 mmol) were dissolved in dimethylformamide (5 mL) and cooled to 0° C. tert-Butylchlorodiphenylsilane (1.34 g, 4.87 mmol) was added dropwise at 0° C. The reaction mixture was allowed to warm to room temperature and stirred for 5 hours. The mixture was was poured into 0.5 N HCl (50 ml), and the resultant mixture was extracted with ethyl acetate. The layers were separated, and the organic phase was washed with saturated sodium bicarbonate, water and brine. The organic phase was dried over sodium sufate and the solvent removed to afford crude material that was purified on a silica gel column (50% ethyl acetate in hexanes) to give the title compound (1.28 g, 74.0%). 1H NMR (300 MHz, DMSO-d6) δ: 1.0 (s, 9H) 3.3-3.6 (m, 2H) 3.6-3.9 (m, 2H) 4.6-4.8 (m, 1H) 7.3-7.8 (m, 11H). MS (ES) (M+23)+: 278 for the Na+ adduct of C20H25NO3Si.
