Versuchsvorschrift

2-[Benzothiazol-2(3H)-ylidene]-2-(pyrimidin-2-yl)acetonitrile (0.1 g, 0.39 mmol) was dissolved in concentrated sulfuric acid (2 mL) and stirred at room temperature for 5 hr. The mixture was cooled to 0° C., poured over ice, and neutralized with 50% aqueous sodium hydroxide. The precipitate that formed was collected by filtration and purified by reverse phase preparative HPLC to give 2-[benzothiazol-2(3H)-ylidene]-2-(pyrimidin-2-yl)acetamide (42 mg, 40% yield) as a yellow solid.
