Versuchsvorschrift

2-Methyl-1,2,5-thiadiazole-3-one (11.6 g., 0.1 mole) was dissolved in dry methylene chloride (100 ml.) and under a nitrogen atmosphere was added methyl fluorosulfonate (8.2 ml., 0.1 mole) and the reaction mixture was stirred at room temperature for 1 hour. Further, methyl fluorosulfonate (0.1 ml.) was added and the reaction continued at reflux for one further hour. The reaction was cooled, the precipitate separated by filtration and washed with several portions of cold methylene chloride. Yield 13 g. The compound was stored in a dry atmosphere, m.p., 138°-139° C.
