Versuchsvorschrift

To 1-Benzyl-4-(4-chloro-phenylamino)-piperidine-4-carbonitrile (1.97 g, 6.05 mmol) was added concentrated sulfuric acid (50 ml). The reaction stirred at room temperature as an orange homogeneous solution. After 24 hours the reaction was cooled to 0° C. and very slowly poured into concentrated ammonium hydroxide in ice. The precipitate was filtered and washed with water to give a white solid (202 mg, 71%).
