Versuchsvorschrift
To a solution of 1-benzyl-3-methylpyrrolidin-3-ol (1.0 g, 5.2 mmol) in acetonitrile (10 mL) at 0° C., was added concentrated sulfuric acid (10 mL) slowly. After being stirred for 16 hours at room temperature, the reaction mixture was poured into ice-water. After the reaction mixture was adjusted to pH 7 with a saturated aqueous solution of potassium carbonate, the resulting mixture was exacted with dichloromethane (200 mL×3). The combined organic layers were dried over sodium sulfate, and concentrated in vauo. The residue was purified by preparative HPLC to afford 600 mg of the product (yield was 50%).
