PROCEDURE

实验过程

13.6 g of freshly dried tetrabutylammonium azide are added to a solution, stirred at room temperature, of 17.8 g of 3(S)-isopropyl-5(S)-{1(R)-bromo-4-methyl-3(S)-[(4(S)-benzyloxazolidin-2-on-3-yl)-carbonyl]-pentyl}-tetrahydrofuran-2-one in 180 ml of toluene, and a further 10 g of the azide are added in the course of 160 hours' stirring at room temperature. The reaction mixture is then partitioned between ethyl acetate and water (2×) and saturated sodium chloride solution (1×). The organic phases are combined, dried over sodium sulfate and concentrated. The title compound is obtained from the evaporation residue by means of FC (hexane/ethyl acetate=8:2) and crystallisation from diethyl ether/hexane: m.p.=102°-103° C.; Rf (hexane/ethyl acetate=8:2)=0.2; HPLC Rt =18.55 minutes; FAB-MS (M+H)+ =457.
