Versuchsvorschrift
1 g (5.6 mmol) of 5-phenyl-[1,3,4]thiadiazol-2-ylamine was dissolved in 20 ml of DMF, and 3.1 g (22.6 mmol) of potassium carbonate and 1.1 g (5.6 mmol) of tert-butyl bromoacetate were added. The reaction mixture was stirred at room temperature for 16 h. After evaporation of the solvent under reduced pressure, ethyl acetate was added to the residue. The solution was washed with water, dried with sodium sulfate, filtered, and the solvent was removed under reduced pressure. The product was purified by silica gel chromatography. Yield: 300 mg.
