Versuchsvorschrift
A mixture of 2-(2-(3,4-dimethoxyphenyl)-2-methylpropanoyl)-N-(4-fluorophenyl)-hydrazinecarbothioamide (1.23 g, 3.14 mmol) and 2N NaOH (25 mL) was refluxed overnight. The reaction mixture was cooled to room temperature and acidified with 3N HCl to pH 5. The aqueous solution was extracted with DCM (30 mL×2). The combined organic layers were dried over MgSO4, filtered, and evaporated. The residue was purified by flash chromatography to give the title compound (760 mg, 65%) as a white solid. 1H NMR (400 MHz, CDCl3) δ 12.52 (s, 1H), 6.94-6.90 (m, 2H), 6.70 (d, 1H), 6.60-6.57 (m, 2H), 6.50-6.46 (m, 2H), 3.89 (s, 3H), 3.77 (s, 3H), 1.57 (s, 6H).
