Versuchsvorschrift

A mixture of lithio(trimethylsilyl)acetylene (1.72 mmol) and (S)-N-{3-[4-(4-oxo-piperidin-1-yl)-3-fluorophenyl]-2-oxo-oxazolidin-5-ylmethyl}-acetamide (1.72 mmol) in tetrahydrofuran (10 ml) was stirred at a temperature −78° C. for 15 minutes. It was allowed to come to room temperature and further stirred for 18 hours. The reaction mixture was then stirred with aqueous solution of ammonium chloride, the reaction mixture was extracted with ethyl acetate (3×40 ml). The removal of the solvent provided a residue, which was stirred in aqueous methanolic (15 ml) solution of potassium carbonate (1.72 mmol) for 3 hours. The solvent was removed and the residual mass was purified by column chromatography over silica gel to provide title compound in 19% yield. M.P. 166-167° C. and MS (M+1)=376 (MH+, 100%) M.F.=C19H22FN3O4.
