Versuchsvorschrift
1,3,4-Thiadiazol-2-amine (253 mg, 2.50 mmol) in dimethylacetamide (3 mL) was stirred with phenyl chloroformate (392 μL, 3.13. mmol) at room temperature for one day. After addition of water, the precipitated solid was collected by filtration, washed with water and hexane and dried under reduced pressure to give the title compound as a colorless solid (418 mg, yield 76%).
