Versuchsvorschrift
0.85 ml of triethylamine and 0.53 ml of diphenylphosphoryl azide were added, whilst ice-cooling, to a suspension of 0.30 g of 2-oxothiazolidine-5-carboxylic acid (prepared as described in Preparation 3) and 0.41 g of N-(2-nitrooxyethyl)amine nitrate in 10 ml of dry tetrahydrofuran, and the resulting mixture was stirred at room temperature for 2.5 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 crude crystals thus obtained were triturated with diisopropyl ether, collected by filtration and washed to give 0.40 g of the title compound as a colorless powder, melting at 114°-115° C.
