2-[Benzothiazol-2(3H)-ylidene]-2-[4-tert-butyl-6-(trifluoromethyl)pyrimidin-2-yl]acetonitrile (150 mg, 0.39 mmol) was dissolved in concentrated sulfuric acid (1.5 mL) and stirred at room temperature overnight. The mixture was cooled to 0° C., poured over ice, and neutralized with 50% aqueous sodium hydroxide. The product was partially extracted into chloroform, and dried to a brown solid (57 mg), which was purified by reverse phase preparative HPLC to give 2-[benzothiazol-2(3H)-ylidene]-2-[4-tert-butyl-6-(trifluoromethyl)pyrimidin-2-yl]acetamide (13 mg) as a yellow solid.
