Versuchsvorschrift

0.35 ml of triethylamine and 0.22 ml of diphenylphosphoryl azide were added, whilst ice-cooling and stirring, to a suspension of 110 mg of (5S)-2-oxooxazolidine-5-carboxylic acid (prepared by a procedure similar to that described in Preparation 3) and 170 mg of N-(2-nitrooxyethyl)amine nitrate in 10 ml of dry tetrahydrofuran, and the resulting mixture was stirred at room temperature for 6 hours. At the end of this time, the solvent was removed by distillation under reduced pressure, and the residue was purified by column chromatography through silica gel, using ethyl acetate as the eluent. The pale yellow oil thus obtained was triturated with ethyl acetate, and the resulting precipitate was collected by filtration and washed, to give 79.8 mg of the title compound as a colorless powder, melting at 101°-103° C.
